A 14 kg block is shown in its equilibrium position, suspended from a spring having a stiffness of 80 N/m. Assume the block is given an upward velocity of 0.7 m/s when it is 100 m above its equilibrium position. Determine (a)the natural frequency in rad/s, (b) the natural period in sec, and (c) the amplitude in m.

PART B: Refer to Problem 1 above and determine (a) the magnitude of the maximum velocity in m/s and (b) the magnitude of the maximum acceleration in m/s/s.
