A cyclist going around a circular track at 10.0 m/sm/s has a centripetal acceleration of 5.00 m/s2m/s2 . What is the radius of the curve
Answers
A cyclist going around a circular track at 10.0 m/s^2 has a centripetal acceleration of 5.00 m/s2m/s2 .The radius of the curve is 20.0 meters.
To find the radius of the curve, we can use the formula for centripetal acceleration:
a = (v^2) / r
Where:
a is the centripetal acceleration (given as 5.00 m/s^2)
v is the velocity of the cyclist (given as 10.0 m/s)
r is the radius of the curve (unknown)
Rearranging the formula to solve for r, we have:
r = (v^2) / a
Plugging in the given values:
v = 10.0 m/s
a = 5.00 m/s^2
r = (10.0^2) / 5.00
Calculating the expression:
r = 100 / 5.00
r = 20.0 meters
Therefore, the radius of the curve is 20.0 meters.

Answers
Explanation:
The equation 2y = 8 sin (4πt) is a general equation for a particle vibrating in simple harmonic motion. The amplitude of the oscillations is given by the coefficient of the sine term, which is 8 in this equation. Therefore, the amplitude of the particle vibrating in simple harmonic motion is 8 cm.
The angular frequency is given by the coefficient of the variable t, which is 4π in this equation. Therefore, the angular frequency of the particle vibrating in simple harmonic motion is 4π rad/s.
Therefore, the answer is (b) 4 cm and 4π rad.
The work done on an object is equal to the force times the distance moved in the direction of the force. The velocity of an object in the direction of a force is given by: v = 4t 0≤t≤ 5, 5 ≤t≤ 15 v = 20 + (5-t)² where v is in m/s. With step size h=0. 25, determine the work done if a constant force of 200 N is applied for all t a) using Simpson's 1/3 rule (composite formula) b) using the MATLAB function trapz
Answers
A) Using Simpson's 1/3 rule (composite formula), the work done with a constant force of 200 N is approximately 1250 J.
B) Using the MATLAB function trapz, the work done is approximately 7750 J.
Let's substitute the given values into the Simpson's 1/3 rule formula and calculate the work done using a constant force of 200 N.
A) Force (F) = 200 N (constant for all t)
Velocity (v) = 4t (0 ≤ t ≤ 5) and v = 20 + (5 - t)² (5 ≤ t ≤ 15)
Step size (h) = 0.25
To find the work done using Simpson's 1/3 rule (composite formula), we need to evaluate the integrand at each interval and apply the formula.
Step 1: Divide the time interval [0, 15] into subintervals with a step size of h = 0.25, resulting in 61 equally spaced points: t0, t1, t2, ..., t60.
Step 2: Calculate the velocity at each point using the given expressions for different intervals [0, 5] and [5, 15].
For 0 ≤ t ≤ 5: v = 4t For 5 ≤ t ≤ 15: v = 20 + (5 - t)²
Step 3: Compute the force at each point as F = 200 N (since the force is constant for all t).
Step 4: Multiply the force and velocity at each point to get the integrand.
For 0 ≤ t ≤ 5: F * v = 200 * (4t) For 5 ≤ t ≤ 15: F * v = 200 * [20 + (5 - t)²]
Step 5: Apply Simpson's 1/3 rule formula to approximate the integral of the integrand over the interval [0, 15].
The Simpson's 1/3 rule formula is given by: Integral ≈ (h/3) * [f(x0) + 4f(x1) + 2f(x2) + 4f(x3) + 2f(x4) + ... + 4f(xn-1) + f(xn)]
Here, h = 0.25, and n = 60 (since we have 61 equally spaced points, starting from 0).
Step 6: Multiply the result by the step size h to get the work done.
Work done: 1250 J
B) % Define the time intervals and step size
t = 0:0.25:15;
% Calculate the velocity based on the given expressions
v = zeros(size(t));
v(t <= 5) = 4 * t(t <= 5);
v(t >= 5) = 20 + (5 - t(t >= 5)).^2;
% Define the force value
F = 200;
% Calculate the work done using MATLAB's trapz function
\(work_t_r_a_p_z\) = trapz(t, F * v) * 0.25;
% Display the result
disp(['Work done using MATLAB''s trapz function: ' num2str(\(work_t_r_a_p_z\)) ' J']);
The final answer for the work done using MATLAB's trapz function with the given force and velocity is:

The astronaut somehow accidentally bumps into the soyuz space( the one the crew rode up to the iss) and the capsule breaks free of its dock. Which statement describes the motion of the capsules after it breaks free of the iss but before the panicked astronaut are able to retrieve it?
Answers
The motion of the Soyuz capsule after it breaks free of the ISS but before the panicked astronaut retrieves it can be described as an initial state of zero velocity and a free-fall motion caused by gravity.
When the Soyuz capsule breaks free of the ISS, it has an initial velocity of zero relative to the ISS. Since there is no air resistance in space, the only force acting on the capsule is gravity, which causes it to fall towards the Earth. The motion of the capsule can be described as a free-fall motion until some other force, such as atmospheric drag, slows it down or stops it.

Answer:
Answer: C. 3000kg
Explanation:
Hydraulic Jack
It's a device that is used to lift heavy loads by applying force via a hydraulic cylinder.
Since the internal pressure on the liquid of the jack is constant, the following relation applies:
\(\displaystyle \frac{F_1}{A_1}=\frac{F_2}{A_2}\)
Where
F1 = Force applied in one end of the jack
A1 = Area of the cylinder of the same end
F2 = Force applied in the other end of the jack
A2 = Area of the cylinder of the other end
If we assume the force is being applied on side 1, then the force on side 2 is calculated by solving for F2:
\(\displaystyle F_2=\frac{F_1.A_2}{A_1}\)
We have F1=1000N, A1= 48~cm^2, A2= 1440~cm^2, thus:
\(\displaystyle F_2=\frac{1000.1440}{48}\)
\(F_2 = 30000 ~N\)
Since we need to know the mass that can be lifted by that force, we use the formula:
W = m.g
Where W is the weight of the mass and g= 10~m/s^2. Since the weight is equal to the force exerted by the jack:
\(\displaystyle m=\frac{W}{g}=\frac{30000}{10}\)
m = 3000 Kg

A solid sphere and a hollow sphere, both uniform and having the same mass and radius, roll without slipping toward a hill with the same forward speed V. Which sphere will roll farther up the hill?
Answers
The solid sphere and the hollow sphere will have different rolling motions due to their different moments of inertia. The moment of inertia of a solid sphere is greater than that of a hollow sphere with the same mass and radius because the solid sphere has more mass distributed further from its axis of rotation.
As a result, the solid sphere will roll slower than the hollow sphere, but will have more rotational energy and be able to roll farther up the hill due to its greater inertia.
Therefore, the solid sphere will roll farther up the hill than the hollow sphere, even though they have the same mass and radius and are rolling with the same forward speed V.

The Uniform Circular Motion Interactive is a tool that allows users to explore the physics of uniform circular motion. The user can change the radius of the circle, the speed of the object, and the mass of the object.
When an object moves in a circle at a constant speed, it is said to be in uniform circular motion. The velocity of the object is constantly changing direction, even though the speed is constant. This means that the object is accelerating.
The acceleration of an object in uniform circular motion is directed towards the center of the circle. The magnitude of the acceleration is equal to the square of the speed of the object divided by the radius of the circle.
The net force on an object in uniform circular motion is always directed towards the center of the circle. The magnitude of the net force is equal to the mass of the object times the acceleration of the object.
The Uniform Circular Motion Interactive is a valuable tool for understanding the physics of uniform circular motion. It allows users to explore the effects of changing the radius of the circle, the speed of the object, and the mass of the object on the velocity, acceleration, and net force of the object.

An eraser is thrown upward with an initial velocity of 5.0 m/s. The eraser's velocity after 7.0 seconds is ____ m/s.
Answer: -64
Answers
Given parameters:
Initial velocity of eraser = 5.0m/s
Time = 7.0s
Unknown:
Final velocity = ?
Solution:
Since we have been given the initial velocity and duration of the throw, we can apply the appropriate motion equation to solve this problem.
V = U - 2gt
where V is the final velocity
U is the initial velocity
g is the acceleration due to gravity = 9.8m/s²
t is the time taken
V = U - gt
V = 5 - (9.8)(7)
V = -63.6 or -64m/s
The velocity is -64m/s
As the eraser is thrown upward, its velocity after 7.0 seconds is approximately -64m/s.
Given the data in the question;
Initial velocity of the eraser; \(u = 5.0m/s\)
Final velocity; \(v = \ ?\)
Time; \(t = 7.0s\)
To determine the eraser's velocity after 7.0 seconds, we us the First Equation of Motion:
\(v = u + at\)
Where v is the final velocity, u is the initial velocity, t is the time and a is the acceleration. Since the eraser was thrown upward, acceleration due to gravity becomes ( negative acceleration ) \(g = -9.8m/s^2\)
Hence, the equation becomes
\(v = u - gt\)
We substitute in our values and solve for "v"
\(v = 5.0m/s - ( 9.8m/s^2 \ *\ 7.0s )\\\\v = 5.0m/s - 68.6m/s\\\\v = -63.6m/s\\\\v = -64m/s\)
Therefore, as the eraser is thrown upward, its velocity after 7.0 seconds is approximately -64m/s.

A westward-moving bicycle slows down from 10.0m/s to 4.0m/s. What is the magnitude and direction of the acceleration
Answers
Answer:
a = -6/t (on the opposite direction of the bicycle motion)
Explanation:
For all problems of physics we need to set the positive axis direction. and the origin. In our case the origin location does not make difference since we are only interested in velocities and acceleration. So I'm gonna set the positive axis in the same direction that the bicycle is moving. Therefore, our initial (10 m/s) and final (4 m/s) velocities are also positive.
However we have some problems. We do not know how this bicycle was decelerated (constant or not). Besides we do not have the information like time or displacement of this deceleration.
So, supposing an uniform deceleration and using the velocity time function for uniform "a", we get:
v = vo + at (set the initial time to 0s)
4 = 10 + at
a = -6/t
So you only can determine the acceleration if you have either the time or the displacement (using Torricelli equation). But we know that our bicycle acceleration points against the direction of the bicycle motion due to the negative sign.
