Question 1- The oscillation of rod OA about O is defined by the relation \theta =(3)/(\pi )sin\pi t, where \theta and t are expressed
in radians and seconds, respectively. Collar B slides along the rod so that its distance from O is r=6(2-e^(-3t))
where r and t are expressed in inches and seconds, respectively. When t=2s, determine
(a) the velocity of the collar.
(b) the acceleration of the collar.
