A 4.20 kg block is attached to a spring with spring constant 2140 N/m. The block is resting on a horizontal, frictionless surface. It is pulled 4.20 cm from the equilibrium position and given an initial velocity of 1.00 m/s back toward equilibrium. Notice the block is not released from rest.

A What is the frequency of the motion? Express your answer with the appropriate units.

B. What is the total energy of the block + mass system? Express your answer with the appropriate units.

C What is the amplitude of the motion?
