... A 0.5 kg ball is dropped to the floor from a height of 2 m. If it bounces back to a height of 1.8 m, what is the magnitude of its change in momentum? Some energy is lost in the bounce. Just before it hits the ground, its velocity is: (use conservation of ME) mgh=1/2mv2 so v=(2gh)=(2*9.8*2)= 6.26 m ...
