Math Problem Statement
A block of mass m = 0.72 kg attached to a spring with force constant 137 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.) The left end of a horizontal spring is attached to a vertical wall, and the right end is attached to a block of mass m which can slide left and right on a horizontal surface. The spring is stretched from its equilibrium position by a distance A. (a) At that instant, find the force on the block. (b) At that instant, find its acceleration.
