Because just before the pogo stick contacts the ground the system has its greates velocity.

2.) A

Because they have the same mass and the same height.

3.) D

Because the velocity is 0 (KE is 0), The Height is 0 (GPE = 0) and the spring is compressed due to converting all the kinetic enrgy into SPE.
