The pinion A of the hoist motor drives gear B, which is attached to the hoisting drum. The load L is lifted from its rest position and acquires an upward velocity of 3 [ft/sec] in a vertical rise of 4 [ft] with constant acceleration. As the load passes this position, compute (a) the acceleration (in [ft/sec^2]) of point Con the cable in contact with the drum and (b) the angular velocity (in [rad/sec]) and angular acceleration (in [rad/sec^2]) of the pinion A.
