A 0.150-kg air track cart is attached to an ideal spring with a force constant (spring constant) of 3.58 N/m and undergoes simple harmonic oscillations. What is the period of the oscillations?
 
  A) 2.57 s
  B) 0.527 s
  C) 0.263 s
  D) 1.14 s
  E) 1.29 s

Question 2

The position of an object that is oscillating on an ideal spring is given by x = (17.4 cm) cos(5.46 s-1)t. Write an expression for the acceleration of the particle as a function of time using the cosine function.
 
  What will be an ideal response?
