A 2-kg ball B is traveling horizontally at 3 m/s when it strikes 2-kg ball A. Ball A is initially at rest and is attached to a spring with constant 15 N/m and unstretched length of 1.2 m. Knowing the coefficient of restitution between A and B is 0.9 and friction between all surfaces in negligible, determine the normal force between A and the ground when it is at the bottom of the hill.
