2. The small eylinder is made to move along the rotating rod with a motion between r = vy + b and r = rg b given by r = rq + bcos (M), where t is the time counted from the instant the cylinder passes the position and 7 is the = period of the oscillation (time for one complete oscillation). Simultaneously, the rod rotates about the vertical at the non-constant angular rate (#). Calculate velocity and acceleration of the small cylinder. (30) Figure 2: The rotating rod
