) A 2 kg block is attached to a rope. The rope is wound around a pulley which has a radius of 0.2 m. You do not know the mass of the pulley, or the geometry of the pulley. The block is released from rest, and you notice it has a speed of 3 m/s after falling 1.5 m. a) What is the angular velocity of the pulley when the speed is 3 m/s? b) Use the fact that energy is conserved to find the moment of inertia of the pulley. You must use energy conservation to receive full marks. c) What is the torque applied to the pulley and the tension in the cable?

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)?

In the figure below, a rope is wound around a horizontal disk (Ma 3.10 kg and Ra 17.0 cm). passed across a pulley (Ic 50.0 kg cm2 and Re 8.00 cm), and connected to a hanging 4.00 kg mass. Initially, the mass is held in place, and the system is at rest. The mass is then released and descends in response to the force of gravity. The rope does not slip on the pulley or the horizontal disk. Both the...

A 12.0 kg object is attached to a cord that is wrapped around a
wheel of radius 10.0 cm. The acceleration of the object down the
frictionless incline is measured to be 2.00 m/s2. Assuming the axis
of the wheel to be frictionless, determine a) the tension in the
rope, b) the moment of inertia of the wheel, and c) the angular
speed of the wheel 2.00 s after it begins rotating, starting from
rest.

A hanging weight, with a mass of me = 0.350 kg, is attached by a rope to a block with mass m2 = 0.820 kg as shown in the figure below. The rope goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R2 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As...

A box of mass m = 10.0 kg is attached to a rope. The other end of the rope is wrapped around a pulley with a radius of 15.0 cm. When you release the box, it begins to fall and the rope around the pulley begins to unwind, causing the pulley to rotate. As the box falls, the rope does not slip as it unwinds from the pulley. If the box is traveling at a speed of 2.50 m/s after...
