A 2.25-kg object is attached to a horizontal an ideal massless spring on a frictionless table. What should be the spring constant of this spring so that the maximum acceleration of the object will be g when it oscillates with amplitude of 4.50 cm?
 
  What will be an ideal response?

Question 2

A 1.6-kg block on a horizontal frictionless surface is attached to an ideal massless spring whose spring constant is 190 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. What is the velocity of the block at time
  t = 0.40 s?
  A) 0.82 m/s
  B) -0.82 m/s
  C) 0.30 m/s
  D) -0.30 m/s
  E) 0.00 m/s
