Walker, Halliday & Resnick — Center of Mass and Linear Momentum: Problem 21
21 A ball of mass 50 g moving with a speed of 2.0 m/s strikes a wall at an angle of incidence 45° and is reflected from the wall at the same angle and with the same speed. See the overhead view in Fig. 9-38. Calculate (a) the magnitude of the change \(\Delta \vec{p}\) in the momentum of the ball, (b) the change in the magnitude of the momentum of the ball, and (c) the change in the magnitude of the momentum of the wall.
📝 Solution Approach
Given: 21 A, 50 g, 2.0 m
Find: (a) the magnitude of the change \; (b) the change in the magnitude of the momentum of the ball; (c) the change in the magnitude of the momentum of the wall
