5. Apply Scientific Reasoning You have two identical tennis balls swinging on strings of the same length. At the lowest point in their Ball B. Which ball will swing to a higher point, paths, Ball A moves three times as fast as and how much higher will it go? Explain.

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
