A cylinder of radius R = 1 (m) can freely rotate around its axis. The force F = 20t – 5t? (N) applied tangentially to the lateral surface of the cylinder changes with time. The cylinder is initially at rest and its moment of inertia is 5 (kg.m). How many cycles does the cylinder make before it starts rotating in the opposite direction? Take 1=3.
