A spring (spring constant = 112 N/m) is mounted on the floor and is oriented vertically.

A spring (spring constant = 112 N/m) is mounted on the floor and is oriented vertically. A 0.400 kg block is placed on top of the spring and pushed down to start it oscillating in simple harmonic motion. The block is not attached to the spring. a) obtain the frequency (in Hz) of the motion.b) determine the amplitude at which the block will lose contact with the spring.
