PE∝h

KE∝v

2

a)At max point, Potential energy due to height and no kinetic energy because it has no velocity

(b) Both Potential energy and kinetic energy , because it have both height and velocity.

(c) only Kinetic energy enrgy , because height from ground is zero.

hope you have great day ahead...
