Solution: A 205 kg block is released at a 6.3 m height as shown. The track is frictionless. The block travels down the track, hits a spring of force constant k = 1285 N/m . The acceleration of gravity is 9.8 m/s2. Determine the compression of the spring x from its equilibrium position before coming to rest momentarily.
