The figure below shows a ball with mass m = 0.402 kg attached to the end of a thin rod with length L = 0.506 m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod Is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically up position, with zero speed there (a) What initial speed must be given the ball so that it reaches the vertically upward position with zero speed? m/s (b) What then is its speed at the lowest point? m/s (c) What then is its speed at the point on the right level with the Initial point? m/s If the ball's mass were doubled, would the answers to (a) through (c) increase, decrease, or remain the same? O increase O decrease O remain the same

i know how to calculate compress with a given spring constant but never one where the object was falling from a certain distance onto the spring? there are no steps in the book for this practice problem
ASK YOUR TEACHER The figure below shows a ball with mass m = 0.402 kg attached to the end of a thin rod with length L = 0.506 m and negligible mass. The other end of the rod Is pivoted so that the ball can move In a vertical circle. The rod is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically up position, with zero speed there. (a) What initlal speed must be given the ball so that it reaches the vertically upward position with zero speed? m/s (b) What then is its speed at the lowest point? m/s (c) What then is its speed at the point on the right level with the initlal point? m/s If the ball's mass were doubled, would the answers to (a) through (c) Increase, decrease, or remain the same?
