In parts (a) and (b) of Problem 23 determine whether the mass passes through the equilibrium position. In each case find the time at which the mass attains its extreme displacement from the equilibrium position. What is the position of the mass at this instant?

Problem 23

(a) The mass is initially released from rest from a point 1 meter below the equilibrium position, and then

(b) The mass is initially released from a point 1 meter below the equilibrium position with an upward velocity of 12 m/s.
