일반물리학 1 — Potential Energy and Conservation of Energy: Problem 16

16 A 700 g block is released from rest at height \( h_0 \) above a vertical spring with spring constant \( k = 450 \text{ N/m} \) and negligible mass. The block sticks to the spring and momentarily stops after compressing the spring 19.0 cm. How much work is done (a) by the block on the spring and (b) by the spring on the block? (c) What is the value of \( h_0 \)? (d) If the block were released from height \( 2.00h_0 \) above the spring, what would be the maximum compression of the spring?
