Question 2

A 0.28-kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 500 N/m. The block is pulled from its equilibrium position at x = 0.00 m to a displacement x = +0.080 m and is released from rest.
 
  The block then executes simple harmonic motion along the horizontal x-axis. When the displacement is x = -0.052 m, find the acceleration of the block. A) 92 m/s2
  B) 46 m/s2
  C) 69 m/s2
  D) 230 m/s2
  E) 280 m/s2
