A vertical spring with a constant of 370 N/m is mounted on the floor. From directly above the spring, which is unstrained, a 0.29 kg block is dropped from rest. It collides with sticks to the spring, which is cpmpressed by 3.3 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?

70 N/m is mounted on the floor. From directly above the spring, which is unstrai
is compressed by 3.3 cm in bringing the block to a momentary halt. Assuming a
k dropped?
