A machine part is vibrating along the x-axis in simple harmonic motion with a period of 0.27 s and a range (from the maximum in one direction to the maximum in the other) of 3.0 cm.
 
  At time t = 0 it is at its central position and moving in the +x direction. What is its position when t = 55 s? A) x = -0.43 cm
  B) x = -0.51 cm
  C) x = +0.51 cm
  D) x = -1.3 cm
  E) x = -1.4 cm

  A) 7.9 N/C
  B) 3.9 N/C
  C) 0.49 N/C
  D) 0.031 N/C
