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
Ths,
change in momentum of ball will be zero.

- Two hockey players of opposite teams, while trying to hit a hockey ball on the ground collide and immediately become entangled. One has a mass of 60 kg and was moving with a velocity 5.0 m s–1 while the other has a mass of 55 kg and was moving faster with a velocity 6.0 m s–1 towards the first player. In which direction and with what velocity will they move after they become entangled? Assume that the frictional force acting between the feet of the two players and ground is negligible.
