A2 kg ball b is travelling horizontally at 10 m/s when it strikes 2 kg ball a. ball a is initially at rest and is attached to a spring with constant 100 n/m and an unstretched length of 1.2 m. knowing the coefficient of restitution between a and b is 0.8 and friction between all surfaces is negligable, determine the normal force between a and the ground when it is at the bottom of the hill.
