The diagram below is showing the motion and position of ball-A and ball-B. Both balls were lifted up in the air to the same height and at the same time. If ball -B is heavier than ball-A, then ball-B would accelerate towards the ground. Answer the following questions:

a- Which of the above balls has maximum Gravitational Potential energy? _

b- Which of the above balls has maximum Kinetic energy? _

c- Which of the above balls is losing its Gravitational Potential energy first? _

d- Which of the above balls would lose all its Kinetic energy first? _

e-After losing all their G. P.E and K. E, both of the balls would become stationary and now they would have only _ energy.
