A block of mass m = 0.875 kg is fastened to an unstrained horizontal spring whose spring constant is k = 81.3 N/m. The block is given a displacement of +0.134 m, where the + sign indicates that the displacement is along the +x axis, and then released from rest.
a) What is the force (with sign) that the spring exerts on the block now before the block is released?
b) Find the angular frequency of the resulting oscillatory motion.
c) What is the maximum speed of the block?
d) Decide the magnitude of the maximum acceleration of the block.
