Make upward positive. A ball of mass 9.49 kg is released from rest at height 9.45 m above the floor. It falls, hits the ground, and rebounds to height 3.14 m above the floor. Assume none of the losses are due to air friction. Find the impulse, in N-s, exerted by the floor on the ball. The sign of your answer will give the direction of the impulse.
In the given problem Impulse can be calculate using below formula
Impulse=Momentum of the ball after collision - Momentum of the ball before collision with floor
Impulse, I=203.46 N.s Upward direction
