"An object is moving along the x-axis in simple harmonic motion. It starts from its equilibrium position which is at the origin at t=0 and is moving to the right. The amplitude of its motion is 2 m and its frequency is 3 hz. (1) Determine the expression for the objects displacement. (2) Where is the object located at t=1.0 s? (3) What is the maximum value of acceleration?(adsbygoogle = window.adsbygoogle || []).push({});

For 1, using the the general SHM expression, I got x=(2 m) cos (6pi(t) + pi/2)

But for (2), plugging in 1 sec., i get 2 m. After 1 sec, shouldn't the object be back at the origin?

For (3), i would really appreciate a hint.

regards
