A pendulum has a swinging motion such that = [ - 0.101 sin(4.95t) + 0.3 cos(4.95t)

A pendulum has a swinging motion such that θ = [ - 0.101 sin(4.95t) + 0.3 cos(4.95t) ] rad, where t is in seconds, and the arguments for the sine and cosine are in radians. Determine the magnitudes of the velocity and acceleration of the bob when θ = 0°.
