Explain how please. A 15 kg block is attached to a rope that is wrapped many times around the rim of a flywheel (pulley) of radius 0.2 meters. When the block is released the rope unspools without slipping. If the acceleration of the block is 3.5, what is the rotational inertia of the flywheel (in kg·m2)?

    A block (mass = 2.2 kg) is hanging from a massless cord that is wrapped around a pulley (moment of inertia = 1.6 x 10-3 kg·m2), as the figure shows. Initially the pulley is prevented from rotating and the block is stationary. Then, the pulley is allowed to rotate as the block falls. The cord does not slip relative to the pulley as the block falls. Assume that the radius of the cord around the pulley remains constant at a...

    A block of mass M = 1.1 kg is attached to a string which is wrapped around a pulley. As the block accelerates due to gravity the pulley rotates clockwise. The pulley can be thought of as a thin cylinder of mass m = 0.5 kg and radius r = 0.26 m. Consider positive to be the block moving down and the pulley rotating clockwise. What is the downwards acceleration of the block? What is the angular acceleration of the...
