Statement of a problem № 10283


A 285-g ball falls vertically downward, hitting the floor with a speed of 2.5 m/s and rebounding upward with a speed of 2.0 m/s. (a) Find the magnitude of the change in the ball s momentum. (b) Find the change in the magnitude of the ball s momentum. (c) Which of the two quantities calculated in parts (a) and (b) is more directly related to the net force acting on the ball during its collision with the floor? Explain.
