Question

Consider the falling and rolling motion of the ball in the following situations (where PE is potential energy, and KE is kinetic energy). IT-100 KE-OJ FE:50] FPJ IT ve Hws In one situation, the ball falls off the top of the platform to the floor. In the other situation, the ball rolls from the top of the platform along the staircase-like pathway to the floor. For each situation, fill in the blanks for the 2 kg ball. Note: Write a maximum of 2 decimal points (i.e., if answer is 1.0111 write 1.01)
