A 700 g block is released from rest at height h0 above a vertical spring with spring constant k = 455 N/m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 23.0 cm. (c) What is the value of h0? (d) If the block were released from height 2.00h0 above the spring, what would be the maximum compression of the spring?
