dye You release a steel ball with a mass of 2 kg. from rest at point A one meter above the center of a steel plate, which has a mass of 8 kg. The plate is suspended by four bungee cords, each having a spring constant k = 100 N/m. The coefficient of restitution between the ball and the plate, e, is 0.9. How far down will the plate travel after impact, and how high above the plate's initial suspended...
