Explanation:

The amount of work done by a person lifting a 6.7-kg object from the bottom of a well at a constant speed of 2.5 m/s for 9 s is 1517.25 Joules.

The work done is determined using the equation below;

W = FdW = mgd

Where,W = Work done by the person,m = mass of object = 6.7 kg,g = acceleration due to gravity = 9.8 md = distance lifted by the person = ?We know that F = m(g + a) where a is the acceleration of the object that was lifted. The object is lifted at a constant velocity and so the acceleration of the object is zero. Hence,

F = mgF = 6.7 × 9.8F = 65.66 N

We can now determine the distance d that was lifted using the equation below;

d = vt

Where,v = constant velocity = 2.5 m/s.t = time taken = 9 s

Substituting the values; d = 2.5 × 9d = 22.5 m

Now we can determine the work done;

W = FdW = 65.66 × 22.5W = 1472.85 Joules (3 decimal places)

The work done by the person lifting a 6.7-kg object from the bottom of a well at a constant speed of 2.5 m/s for 9 s is 1517.25 Joules (2 decimal places)Answer: 1517.25 Joules.

It will take 2.857 minutes (or about 2 minutes and 51 seconds) for the fish to reach a temperature of 60 °C.

To determine the time it will take for the fish to reach a temperature of 60 °C, we can use the principle of heat conduction and the concept of temperature difference.

We know that the rate of heating by conduction is proportional to the temperature difference between the body and its surroundings. Therefore, we can write the following equation:

(T - Ts) = k * t

where T is the temperature of the fish, Ts is the temperature of the surroundings (boiling water), k is the proportionality constant, and t is the time.

Given that the initial temperature of the fish is 20 °C and it takes 5 minutes to reach 30 °C, we can substitute these values into the equation:

(30 - 100) = k * 5

-70 = 5k

Solving for k, we find k = -14.

Now we can use this value of k to find the time it will take for the fish to reach 60 °C:

(60 - 100) = -14 * t

-40 = -14t

Dividing both sides by -14, we get t = 2.857 minutes.

Given that the initial speed of the car is 20 m/s.

The car comes to a stop and the maximum deceleration of the car is 10 m/s².

Part A

To find the distance between the deer and the car when it comes to a stop, we need to find the distance traveled by the car after the brakes are applied.Using the formula:

v² = u² + 2

as where v = 0 (final velocity), u = 20 m/s (initial velocity), a = -10 m/s² (deceleration) and s = distance traveled by the car after the brakes are applied.

0² = 20² + 2(-10)s=> 0 = 400 - 20s=> s = 400/20= 20 m

The distance between the car and deer is 41 m. Therefore, the distance between the car and deer when the car comes to a stop is:

Distance between car and deer = 41 m - 20 m = 21 m.

Part B

We can use the same formula to find the maximum speed at which the car should travel to avoid hitting the deer.

The maximum distance that the car travels after the brakes are applied should be equal to the distance between the car and deer.

v² = u² + 2aswhere v = 0 (final velocity), u = maximum speed, a = -10 m/s² (deceleration) and s = 41 m (distance between car and deer).

0² = u² + 2(-10)(41)=> 0 = u² - 820=> u² = 820=> u = √820 = 28.64 m/s

Therefore, the maximum speed at which the car should travel to avoid hitting the deer is 28.64 m/s.

The recoil velocity of the cannon would be  1.85 m/s to the left.

Let's assume that the positive direction is to the right. The initial momentum of the system (cannon + ball) is:

p_initial = m_cannon * 0 m/s + m_ball * 88 m/s = 0 + 12 kg * 88 m/s = 1056 kg*m/s

After the ball is fired, the momentum of the cannon and the ball must be equal and opposite to conserve momentum. Let's assume that the recoil velocity of the cannon is v_cannon:

p_final = m_cannon * v_cannon + m_ball * 0 m/s = 0 + 12 kg * 0 m/s = 0

Using the conservation of momentum equation, we can set the initial momentum equal to the final momentum:

p_initial = p_final

m_cannon * 0 m/s + m_ball * 88 m/s = m_cannon * v_cannon + m_ball * 0 m/s

Solving for v_cannon, we get:

v_cannon = (m_ball/m_cannon) * 88 m/s

v_cannon = (12 kg / 568 kg) * 88 m/s

v_cannon = 1.85 m/s (to the left)

The number of floors from the 12th floor that the ball should descend in 3s is 9 when a ball is released from rest from the twentieth floor of a building.

From Newtons laws of motion we know that S = ut + 1/2at^2

where u denotes initial velocity, t denotes time taken, a denotes acceleration of the body and s denotes distance.

Given t = 1s, u = 0m/s since at rest and a = g = 9.8m/s^2

Then S = 0x1 + 1/2x9.8x1x1 = 4.9m

So the height of first floor == 4.9m

Then after 3s the distance covered by ball is S = ut +1/2at^2

S = 0x3 + 1/2x9.8x3x3 = 44.1m

Hence the distance covered by ball after 3s is 44.1m

Then the number of floor covered = 44.1/4.9 = 9

Therefore, we can conclude that the 9th floor is the floor from which the ball should descend in 3s starting on the 12th floor.

Explanation:

Refer to the diagram attached. There are two forces on this tetherball: tension \(T\) in the string, and weight \(m\, g\)- where \(m\) is the mass of the tetherball.

Let \(T\) denote the tension in the string, and let \(\theta = 12^{\circ}\) denote the angle of elevation of this force. Decompose \(T\!\) into two components: horizontal and vertical:

The tetherball is moving in a horizontal plane, meaning that there is no motion in the vertical direction. Hence, the resultant force in the vertical direction should be \(0\). The vertical component of the tension \(T\, \sin(\theta)\) should exactly balance the weight of the tetherball \(m\, g\):

\(T\, \sin(\theta) = m\, g\).

Hence, the resultant (unbalanced) force on this tetherball would be equal to the horizontal component of tension: \(F_{\text{net}} = T\, \cos(\theta)\).

The length of the rope is \(l = 1.55\; {\rm m}\). Since this rope is also at the angle of \(\theta\) above the horizon, the radius of the circular motion in the horizontal plane would be \(r = l\, \cos(\theta)\).

Since the ball is in a centripetal motion, the resultant force on this ball would also be \(F_{\text{net}} = (m\, v^{2}) / (r)\), where \(v\) is the velocity of the ball.

Equate these two expressions of \(F_{\text{net}}\) to obtain:

\(\displaystyle T\, \cos(\theta) = F_{\text{net}} = \frac{m\, v^{2}}{r}\).

Additionally, \(T\, \sin(\theta) = m\, g\) since the forces on the vertical direction are balanced. Rewrite both this equation and the equation \(T\, \cos(\theta) = (m\, v^{2}) / (r)\) to isolate tension \(T\):

\(\left\lbrace \begin{aligned}& T\, \cos(\theta) = \frac{m\, v^{2}}{r} \\ &T\, \sin(\theta) = m\, g\end{aligned}\right.\).

\(\left\lbrace \begin{aligned}& T = \frac{m\, v^{2}}{r\, \cos(\theta)} \\ &T = \frac{m\, g}{\sin(\theta)}\end{aligned}\right.\).

Solve this system for velocity \(v\):

\(\begin{aligned}\frac{m\, v^{2}}{r\, \cos(\theta)} &= \frac{m\, g}{\sin(\theta)}\end{aligned}\).

Since \(r = l\, \cos(\theta)\):

\(\begin{aligned}\frac{m\, v^{2}}{l\, \cos(\theta)\, \cos(\theta)} &= \frac{m\, g}{\sin(\theta)}\end{aligned}\).

\(\displaystyle \frac{m\, v^{2}}{l\, \cos^{2}(\theta)} = \frac{m\, g}{\sin(\theta)}\).

\(\begin{aligned}v &= \sqrt{\frac{g\, l\, \cos^{2}(\theta)}{\sin(\theta)}} \\ &\approx \sqrt{\frac{9.81\, (\cos(12^{\circ}))^{2}}{(1.55)\, \sin(12^{\circ})}}\; {\rm m\cdot s^{-1}} \\ &\approx 5.40\; {\rm m\cdot s^{-1}}\end{aligned}\).
