A bowing bat (which can be approximated as a solid sphere of mass m and radius r) rolls without slipping along a ball rack with a linear speed v_1. The ball then rolls up a ramp of height h. At the top of the rack, the ball continues to roll without with a linear speed v_1. a) Use the Work-Energy Theorem to derive an expression for the initial linear speed of the ball (v_1) at the bottom of the ramp....
