Q. A vertical spring with a spring constant of 480 N/m is mounted on the floor. From directly above the spring, that is unstrained, a 0.150 kg block is dropped from rest. It collides with and sticks to the spring, that is compressed by 3.9-cm in bringing the block to a momentary halt. Assuming air resistance is negligible; from what height above the compressed spring was the block dropped.
