A.5 Hz
B.10 Hz
C.14 Hz
D.20 Hz
E.40 Hz


8. A 0.2-kg block is held in place by a force F that results in a 0.10-m compression of a spring beneath the block. The spring constant is 100 N/m. Assuming the mass of the spring is negligible compared to that of the block, to what maximum height would the block rise if the force F were removed?
