A 1.0 kg mass is attached to a string wrapped around a shaft of negligible mass and having a 5.0 cm radius. A dumbbell-shaped "flywheel" made from two .500 kg masses is attached to one end of the shaft and perpendicular to its axis. The mass is released from rest and allowed to fall .8 m to the floor. It reaches a speed of 1.5238 m/s just before striking the floor. How far apart are the masses of the dumbbell?
A light cable is wrapped around a solid cylinder with mass M = 1.50 kg and radius R = 0.20 m as shown in the figure below. The cylinder rotates with negligible friction about a stationary horizontal axis. The free end of the cable is tied to a block of mass m = 0.50 kg. The block, initially at rest, is released at a height h = 1.00 m above the floor. As the block falls, the cable unwinds without...
A weight of mass 1.03 kg is suspended by a string wrapped around a pulley wheel, which consists of a solid disk of mass 4.96 kg and radius 1.37 m. The system is released from rest. Over what vertical distance does the hanging mass move in 3.0 seconds?
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...
A weight of mass 1.66 kg is suspended by a string wrapped around a pulley wheel, which consists of a solid disk of mass 4.03 kg and radius 0.603 m. The system is released from rest. Over what vertical distance does the hanging mass move in 3.0 seconds? Ignore friction and drag forces, and assume that the string does not slip.

A 2.20 kg mass is attached to a light cord that is wrapped around a pulley of radius 4.35 cm, which turns with negligible friction. The mass falls at a constant acceleration of 2.05 m/s2. Find the moment of inertia of the pulley.
A 1.60 kg mass is attached to a light cord that is wrapped around a pulley of radius 4.75 cm, which turns with negligble friction. The mass falls at a constant acceleration of 3.40 m/s^2. Find the moment of inertia of the pulley.
An m = 13.6 kg mass is attached to a cord that is wrapped around a wheel of radius r = 11.3 cm (see the figure below). The acceleration of the mass down the frictionless incline is measured to be a = 1.98 m/s2. Assuming the axle of the wheel to be frictionless, and the angle to be theta= 33.0o determine the tension in the rope. Determine the moment of inertia of the wheel. Determine angular speed of the wheel...
an 8kg flywheel of radius r is initially at rest. assume the radius of the gyration kG= 0.12m and the radius of the flywheel r = 0.125m. an object B also of mass 8 kg is attached to a cord that is wrapped around a periphery of the flywheel. the fly wheel starts to rotate clockwise with angular velocity. the rotation is resisted by a constant frictional torque mf in the bearing 1Nm. use the work energy principle to determine...
