A particle moving with constant speed parallel to a smooth

Last updated: 7/10/2022

A particle moving with constant speed parallel to a smooth wall over a smooth horizontal plane is acted upon by an impulse of 2 N-s perpendicular to its motion. The particle of mass 0.5 kg consequently changes its speed to 5 m/s and undergoes a collision with the wall such that after collision the speed becomes 3√2 m/s. Find the value of coefficient of restitution between the particle and the wall.
