A 0.63 kg block attached to a spring with force constant 110 N/m is free to move on a frictionless, horizontal surface as in the figure below. The block is released from rest after the spring is stretched 0.13 m.
(a) At that instant, find the force on the block.
= N
(b) At that instant, find its acceleration.
