Question

Can the person that takes this question please show step by step of how answers were figured. Pls explain each part for me to understand. This is my second request as a person that attempted to assist prior notes/steps were difficult to follow/read. And please use the given equations, since I need to understand how/where/when to use them.
Thank you.

Problem 2, it might help to let you know that you can choose where G.P.E. is non-zero and zero when working with energy in a problem.
For Part (a), it is completely correct to state that the package has non-zero G.P.E. at the top where it has a velocity of 1.25m/s (at some initial height of yinitial,A) , then it has zero G.P.E. the moment the package reaches the bumper (at a final height of 0.0m).

For part (b), you can reset the non-zero and zero points of G.P.E.. It, therefore, is completely correct to state in Part (b) of Problem 2 that the package has non-zero G.P.E. the moment before contacting the bumper (at the initial height of, yinitial,B = 0.950m), then it has zero G.P.E. at the position where the package has completely compressed the bumper and stopped (at a final height of 0.0m).

Angle is not considered.
