A) Describe the difference between strength and power during a squat. Provide a quantitative example that illustrates the difference.
B) During a squat, the weight you have on your shoulders has a certain amount of gravitational potential energy. As you squat down and come to a stop at the bottom of the squat, some of that energy is lost. Where does it go?
a cat runs across a road that is 9 meters (m) wide. it covered this distance in 3 seconds (s). what is the speed of the car?

They decided to measure the amount of frictional force experienced by the model car and the distance it traveled in meters. The scientists were able to evaluate the frictional work using the following data.
