Question

Part A Constants A 144-g baseball moving 29 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 1.02 m/s Determine the basebairs speed after the collision Express your answer to three significant figures and include the appropriate units Value Units Submit Part B Determine the total kinetic energy before the collision. Express your answer to two significant figures and include the appropriate units.
