Oct 08, 2007 · I would also ignore air resistance. The acceleration for the two balls is the same: 9.8 m/s^2 downward. Taking the ground to be y= 0, at time t seconds, the first ball will have height y1(t)= -4.9t^2+ 25t. The second ball will have height y2(t)= -4.9t^2- 25t+ 15. They will pass when those heights are the same: -4.9t^2+ 25t= -4.9t^2- 25t+ 15.

Therefore, it may represent a physical situation such as a ball falling freely (after being thrown up), on striking the ground rebounds with reduced speed after each hit against the ground. Fig. (c) : The (a-t) graph shows that the body gets accelerated for a short duration only.

So at time 0 when the ball is just leaving the hand the Velocity will be at it's maximum. At some time(x) the ball will have no kinetic energy and only potential.. therefore velocity will be 0. At the final time when the ball touches your hand again it will have the same speed as when you first threw it up due to conservation of energy.

A ball is thrown up vertically in still air with a velocity of 2 0 m s − 1. It comes back to ground. It comes back to ground. The velocity-time graph is ( g = 1 0 m s − 2 )
