A particle is moving along a circular path having a radius of 5.3 in. such that its position as a function of time is given by 0= sin 3t, where

0 and the argument for the sine are in radians, and t is in seconds. Determine the acceleration of the particle at 0 = 35°. The particle starts from rest at 0 =0°.
