Jill pulls on a rope to lift a 12 kg pail out of a well, while the clumsy jack watches. For a 10.0 meter segment of the lift, she lifts the bucket straight up at constant speed. How much power is required to complete this task in 5 seconds?

12 N

To calculate the power required to complete the task, we can use the formula:

power = work done / time

First, let's calculate the work done:

work = force * distance

The force required to lift the bucket can be calculated using the weight:

force = mass * gravity

where the mass is 12 kg and the acceleration due to gravity is approximately 9.8 m/s^2.

force = 12 kg * 9.8 m/s^2 = 117.6 N

Now, let's calculate the distance:

distance = 10.0 meters

Next, we can calculate the work done:

work = force * distance = 117.6 N * 10.0 m = 1176 J

Finally, let's calculate the power:

power = work done / time = 1176 J / 5 s = 235.2 W

Therefore, the power required to complete this task in 5 seconds is 235.2 Watts.

To calculate the power required to complete the task, we need to use the formula:

Power = Work / Time

First, we need to calculate the work done. The work done is equal to the force applied multiplied by the distance over which the force is applied. In this case, Jill is applying a force to lift the pail, so the work done is:

Work = Force * Distance

The force can be calculated using Newton's second law, which states:

Force = Mass * Acceleration

Since the pail is lifted at a constant speed, the acceleration is zero. Therefore, the force can be calculated as:

Force = Mass * Acceleration = Mass * 0 = 0

Hence, the force required is zero.

Now we can calculate the work done:

Work = Force * Distance = 0 * 10.0 meters = 0 Joules

Finally, we can calculate the power:

Power = Work / Time = 0 Joules / 5 seconds = 0 Watts

Therefore, the power required to complete this task in 5 seconds is 0 Watts.

1. Power = work / time

2. work = force x distance

3. f = mg

plug in values starting from equation 3 and go up to equation 1. g stands for gravity constant, and m stands for mass. f stands for force.
