A particle is moving along a circular path having a radius of 6 in. such that its position as a function of time is given by θ = sin 3t, where θ and the argument for the sine are in radians, and t is in seconds. Determine the magnitude of the acceleration of the particle at θ = 30°. The particle starts from rest at θ = 0°.
