A sphere of mass m is moving with a velocity (4 hat(i)-hat(j)) m/s hits a surface and rebounds with a velocity (hat(i)+3hat(j)) m/s. The coefficient of restitution between the sphere and the surface is k/16. find the value of k.

A smooth sphere is moving on a horizontal surface with velocity vector 3hat(i) + hat(j) immediately before it hits a vertical wall. The wall is parallel to the vector hat(j) and the coefficient of restitution between the wall and sphere is (1)/(3) . The velocity vector of the sphere after it hits the wall is :-
