A 700 g block is released from rest at heighth0 above a vertical spring by spring constant k = 365 N/m and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 23.0 cm.
1) What is the value of h0?
2) How much work is done by the block on the spring?
3) How much work is done with the spring on the block?
4) If the block were released from height 2.00h0 above the spring, what would be the maximum compression of the spring?
