Physics Web Assign Ch 13 #1

A block of mass m = 0.55 kg is attached to a spring with force constant 109 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 a distance A = 0.13 m. (Indicate the direction with the sign of your answer. Assume that the positive direction is to the right.)

(a) At that instant, find the force on the block.
_____ N

(b) At that instant, find its acceleration.
_____ m/s2
