A 144-g baseball mobing 28.0 m/s strikes a stationary 5.25 kg brick resting on small rollers so it moves without significant friction. After hitting the brick, the baseball bounces straight back, and the brick moves forward at 1.10 m/s.
A). What is the baseball's speed after the collision?
B.) Find the total kinetic energy before and after the collision.
