The final velocity of the airplane is 75.1 m/s.

Velocity can be defined as the measurement of rate and direction of motion.

The velocity of a moving object changes with time. Thus, a moving object will have an initial velocity as well as a final velocity.

The formula for final velocity, V is given by the formula below:

v = √(u² + 2as)

where

The values are as follows:

u = 25.88 m/s

a = 4.21 m/s²

s = 590.39 m

Substituting the values

v = √{(25.88)² + 2 * 4.21 * 590.39)}

v = 75.1 m/s

Therefore, the final velocity, v is 75.1 m/s

In conclusion, the final velocity of the airplane is derived from the initial velocity, acceleration, and distance of travel.

W = -nRT ln(Vf/Vi)

Where:

W is the work done

n is the number of moles of the gas

R is the gas constant (8.314 J/(mol K))

T is the temperature in Kelvin

Vf is the final volume

Vi is the initial volume

Given:

n = 1 mole

R = 8.314 J/(mol K)

T = 20°C

= 293.15 K

Vi = 0.8 m³

Answer:

(a) 0.42 m/s²

(b) 83 N

Explanation:

Assuming g = 10 m/s².

Draw free body diagrams for the child and the chair.

There are three forces on the child:

Tension force T pulling up,

Weight force Mg pulling down,

and normal force N pushing up.

There are three forces on the chair:

Tension force T pulling up,

Weight force mg pulling down,

and normal force N pushing down.

Sum of forces on the child in the y direction:

∑F = ma

T + N − Mg = Ma

Sum of forces on the chair in the y direction:

∑F = ma

T − N − mg = ma

Add the equations together to find the acceleration.

2T − Mg − mg = Ma + ma

a = (2T − Mg − mg) / (M + m)

a = g (2T − Mg − mg) / (Mg + mg)

a = (10 m/s²) (2 × 250 N − 320 N − 160 N) / (320 N + 160 N)

a = 0.42 m/s²

Plug into either equation to find the normal force.

T + N − Mg = Ma

250 N + N − 320 N = (320 N / 10 m/s²) (0.42 m/s²)

N = 83 N

Answer:

Power = 49 W

Explanation:

power = work / time (J/t or watt)

Joule or J = kg*\(m^{2}\)/\(s^{2}\)

watt or W = J/s

given:

mass = 2.0 kg

height = 15 m

g = 9.81 m/s2  (assumed)

t = 6 seconds

work = mass*g*h

work = 2.0*9.81*15 = 294.3 kg*\(m^{2}\)/\(s^{2}\) = 294.3 J

Power = 294.3 J / 6 seconds = 49.1 J/s = 49 W

3. The acceleration of the bicycle is 0.36 m/s²

4. The distance traveled by the person is 2.25 m

5. The initial speed of the car is 7 m/s

The acceleration of the bicycle can be obtained as follow:

v² = u² + 2as

Inputting the given parameters, we have:

6² = 0² + (2 × a × 50)

36 = 0 + 100a

36 = 100a

Divide both side by 100

a = 36 / 100

a = 0.36 m/s²

Thus, the acceleration is 0.36 m/s²

The distance traveled by the person can be obtain as follow:

v² = u² + 2as

1.5² = 0² + (2 × 0.5 × s)

2.25 = 0 + s

s = 2.25 m

Thus, we can conclude that the distance is 2.25 m

The initial speed of the car can be obtain as follow:

v² = u² + 2as

15² = u² + (2 × 2 × 44)

0 = u² + 176

Collect like terms

u² = 225 - 176

u² = 49

Take the square root of both sides

u = √49

u = 7 m/s

Thus, the initial speed of the car is 7 m/s

High-density altitude and high humidity do not ever go hand in hand. If high humidity does exist, however, it exists wise to add 10 percent to your calculated takeoff distance and expect a reduced climb rate.

With a longer takeoff distance, the air exists less dense.

Several elements (altitude/pressure, temperature, and humidity) affect air density. A more elevated altitude, low-pressure area, higher temperature, and increased humidity all contain one effect: they lower the density of the air. And as a consequence of that: a decrease in aircraft and engine performance.

Humidity reduces the implementation of most aircraft, not only because of its effect on the wings but also effect on the engines. Humidity contains a significant effect on the path of plane flies. This exists due to the weight of the air when it exists in humid.

Both springs have a total compression of 2x = 1.5 m.

The force acting on the block is equal to the sum of the forces from both springs. Let x be the compression of each spring.

The force from each spring is given by Hooke's law: F = kx, where k is the spring constant. Since there are two springs, the total force is:

F = 2kx

The force on the block is 600 N, so set up the equation:

2kx = 600

Substituting k = 400 N/m:

2(400 N/m)x = 600 N

The angular velocity of link BD is 2.89 rad/s and the angular acceleration is 0 rad/s².

The expression for angular acceleration can be calculated by applying the vector method.

Here, the vector method of angular velocity will be applied to get the expression for angular velocity ω2 and angular acceleration α2 as follows:

Step 1:Velocity of the collar relative to B and velocity of point A of the link AB and collar can be written as VB = VA + AB X ω1

Here, AB is perpendicular to the plane of rotation, and the velocity of A relative to the collar is ω1 * AB.

Therefore, AB X ω1 = 0 as AB is parallel to AB. Thus, VB = VA.

Then, the velocity of point B can be given as:

VB = BD X ω2Hence, BD X ω2 = VA, we get: ω2 = VA / BD

Step 2: Acceleration of point A relative to collar: AB X α1 = 0 (AB parallel to the plane of rotation)

AA = AB X ω1 X ω1=0

Acceleration of point A relative to C: AC X α1 = AC X 10α2=0

Since, AC=AB=1m

α2=0

Acceleration of collar C relative to point B: BD X α2=VA

Here, α2 = 0, and VB = VA = 5m/s.

Hence:BD * 0 = 5m/sω2 = VA / BD= 5 / (1.732 x 1)=2.89 rad/s

Thus, the angular velocity of link BD is 2.89 rad/s and the angular acceleration is 0 rad/s².
