A ball moving at a constant speed 10m/s, hits normally on a wall (mass of ball is 50g) and rebounds with same speed. The change in momentum is

Expert Answer:

m= 50 g = 0.05 kg 
initial velocity and final veocity are equal 
vf = vi 
Change in momentum = Δp = final momentum - initial momentum = mvf - mvi = m(vf - vi) = 0
change in momentum of ball will be zero.
