The 23 kg cylinder in Problem 15.97 is released from the position shown and falls onto a nonlinear spring. In terms of the spring stretch, S, the potential energy of the spring is given by V = 0.5kS2 + 0.25qS4, where k = 3000 N/m and q = 3600 N/m3. What is the velocity of the cylinder when the spring is compressed 0.3 m?
