A spring with spring constant k = 810 N/m is placed in a vertical orientation with its lower end supported by a horizontal surface. The upper end is depressed 25 cm, and a block with a weight of 29 N is placed (unattached) on the depressed spring. The system is then released from rest. Assume the gravitational potential energy Ug of the block is zero at the release point (y = 0) and calculate the kinetic energy K of the block for y equal to (a) 0, (b) 0.050 m, (c) 0.10 m, (d) 0.15 m, and (e) 0.20 m. Also, (f) how far above its point of release does the block rise?
