Problem 5 (10 points) An inclined plane of angle 0 = 20.0 has a spring of force constant k = 500 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in Figure 1. A block of mass m = 2.50 kg is placed on the plane at a distance d = 0.300 m from the spring. From this position, the block is projected downward toward the spring with initial speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest? Solution: m d. K Figure 1
