A 144-g baseball moving 29m/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 1.22m/s .
A) Determine the baseball's speed after the collision.
B) Determine the total kinetic energy before the collision.
C) Determine the total kinetic energy after the collision.
