**drwls**, Wednesday, July 27, 2011 at 5:17amYou need to know more than math to answer this question. It is about simple harmonic motion.

The amplitude of oscillation is 0.4 m and the period is 1.2 s.

The vertical height at time t is given by

y = 0.5 - 0.4 cos(2 pi t/1.2)

= 0.5 -0.4 cos(5*pi*t/3)

To answer your question, use 0.7 for t.
