Now return to the original cylinder. using newton's 2nd law, complete the equation of motion in the vertical direction j^ that describes the translational motion of the cylinder. express your answer in terms of the tension t in the vertical section of string, m, and g; a positive answer indicates an upward acceleration.

(b) its velocity and its acceleration are both zero. (c) its velocity is perpendicular to its acceleration. (d) its acceleration depends on the angle at which the ball was thrown.
