a ball of mass 4 kg falls to the floor; it lands with a speed of 6 m/s. it bounces off with the same speed. show that its momentum has changed by 48 kg m/s

velocity is a directed value. On its way down, the ball had momentum -24kg-m/s. On its way back up it had momentum +24kg-m/s.

The change is +48kg-m/s

The ball lands to the ground with 6 m/s so, 6 m/s × 4kg = 24kg m/s
It bounce off and goes up so the same 24 change in momentum so 24+24 =48
