Simple harmonic motion: 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
