1. A mass mm = 1.89 kg hangs at the end
of a vertical spring whose top end is fixed to the ceiling. The
spring has spring constant k = 88 N/m and
negligible mass. At time t=0 the mass is released from rest at
a distance d = 0.48 m below its equilibrium
height and then undergoes simple harmonic motion.
