Question:

A 1.00-kg block (M) is on a flat frictionless surface (Fig. 5.32). This block is attached to a spring initially at its relaxed length (spring constant is 50.0 N/m). Alight string is attached to the block and runs over a frictionless pulley to a 450-g dangling mass (m). If the dangling mass is released from rest, how far does it fall before stopping?
