) 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...

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.
