A string holds and wraps around a solid cylinder (7-kg and R
= 8-m). A person pulls the string vertically upward, so the
cylinder's center of gravity does not move and is suspended
in midair for 7 second. Note that the rotational inertia of the
cylinder about its axis is MR2/2, the tension in the string is 8-
N. what is the net force on the cylinder in Newton?
Note: Do not include the unit in your answer.
