Problem
A 2.0kg block is projected downward with a speed of 1.5ms−1 from a point that is 0.60m above the uncompressed top of a vertical spring fixed to the floor. The spring constant is 800Nm−1. Throughout the motion, ignore air resistance.
(i) Calculate the maximum compression produced in the spring.
(ii) Determine the speed of the block at the instant when the spring is compressed by 0.10m.
