A small sphere of mass m = 1 kg is moving with a velocity (4 i ^− j ^ )m/s. It hits fixed smooth wall and rebounds with velocity ( i ^ +3 j ^ )m/s. The coefficient of restitution between the sphere and the wall is n/16. Find the value of n. A particle of mass m makes an elastic head on collision with a stationery particle of mass 2m.

The sphere is resting on a horizontal surface at a distnce 4 m from O. sphere is given a vertical velocity v0 and it moves freely till it reaches point p, when string becomes taut. Find the maximum allowable velocity v0 , if impulse of tension in string is not to exceed 6 N s.A particle of mass m is moving in YZ-plane with a uniform velocity v a with its trajectory running parallel to + ve Y-axis and intersecting Z-axis at z = an in a figure.
