A ball of mass 1 kg moving with a velocity of 5 m/s collides elastically with rough ground at an angle θ with the vertical as shown in Fig. What can be the minimum coefficient of friction if ball rebounds vertically after collision? (given tanθ = 2)

A particle of mass m makes an elastic head on collision with a stationery particle of mass 2m. If initial kinetic energy is moving particle is 6 j then during the impact
