Question
A small ball hits obliquely a smooth and horizontal surface with speed u whose x and y components are 2 amd 4 m/s. If the coefficient of restitution is 1/2, then its x and y components vx and vy just after collision are respectively.
Read 1 Solution.
the velocity along the wall will remain the same as momentum does not change and the other component will be e times that of initial
wall is horizontal so along x = 2 and along y= 1/2 x 4= 2 after collision
