Raul pushes a stalled car with a force of 204 N. If the required force decreases at a constant rate from 204 N to 44.0 N for a distance of 16.3 m in 16.0 s, calculate the average power required to move the car.

204-44=160
160*16.3/16
2608/16
answer: 163 W

To calculate the average power required to move the car, you can use the formula:

Average Power = Work / Time

First, let's calculate the work done. The work done to move an object is given by the formula:

Work = Force * Distance

In this case, the force starts at 204 N and decreases at a constant rate to 44.0 N. We can find the average force by calculating the average of the initial and final forces:

Average Force = (Initial Force + Final Force) / 2

Average Force = (204 N + 44.0 N) / 2 = 124 N

Using the average force and the given distance of 16.3 m, we can calculate the work done:

Work = Average Force * Distance = 124 N * 16.3 m = 2012 N·m

Now, we can substitute the work value and the given time of 16.0 s into the average power formula:

Average Power = Work / Time = 2012 N·m / 16.0 s = 125.75 W

Therefore, the average power required to move the car is approximately 125.75 W.
