A 129-kg block is released at a 5.6 m height as shown. The track is frictionless. The block travels down the track, hits a spring of force constant equal to 1197 N/m. (a) Determine the speed of the block as it hits the spring. (b) Determine the compression of the spring from its equilibrium position when the block comes to rest momentarily.
