A uniform spherical shell of mass M = 20.0 kg and radius R = 0.360 m can rotate about a vertical axis on frictionless bearings (see thefigure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia /= 0.110 kg-m² and radius r = 0.0630m, and is attached to a small object of mass m = 2.20 kg. There is no friction on the pulley's axle; the cord does not slip on the pulley.What is the speed of the object when it has fallen a distance 0.548 m after being released from rest? Use energy considerations.M. RNumberUnits

Two blocks are connected by massless string that is wrapped around a pulley. Block 1 has a mass m1=6.00 kg, block 2 has a mass m2=2.00 kg, while the pulley has a mass of 1.00 kg and a radius of 18.0 cm. When the pulley turns, there is friction in the axel that exerts a torque of magnitude 0.410 N m. If block 1 is released from rest at a height h=1.40 m, how long does it take to drop to the floor?
Two masses are connected by an ideal rope over a pulley. The rope has no mass or stretch. The pulley is frictionless but has mass Mp and radius R. M, is on an approximately frictionless slope with angle 0 =19°. %3D The masses are all equal, M1 = M2 Mp. %3D The pulley can be approximated by a hoop with I = Mp R2 %3D If the masses are released from rest (not moving), what is their speed after M2 has fallen a distance h = 2.4 m?
A block of mass 2 kg slides down an inclined plane at an angle of 45° with a massless tether attached to a pulley with mass 3 kg and radius 0.7 m at the top of the incline (see the following figure). The pulley can be approximated as a disk. The coefficient of kinetic friction on the plane is 0.2. What is the acceleration of the block (in m/s²)? (Enter the magnitude.) 3.59 45° x m/s²
The circular disk of 270-mm radius has a mass of 36 kg with centroidal radius of gyration k⎯⎯k¯ = 235 mm and has a concentric circular groove of 105-mm radius cut into it. A steady force T is applied at an angle θ to a cord wrapped around the groove as shown. If T = 59 N, θ = 29°, μs = 0.08, and μk = 0.07, determine the angular acceleration α of the disk, the acceleration a of its mass center G, and the friction force F which the surface exerts on the disk. The angular acceleration α is positive if counterclockwise, negative if clockwise; the acceleration a is positive if to the right, negative if to the left; and the friction force F is positive if to the right, negative if to the left..

A uniform disk with mass m = 8.75 kg and radius R = 1.41 m lies in the x-y plane and centered at the origin.

Two buckets of mass ?1=17.5 kg and ?2=15.1 kg are attached to the ends of a massless rope which passes over a pulley with a mass of ?p=8.53 kg and a radius of ?p=0.450 m. Assume that the rope does not slip on the pulley, and that the pulley rotates without friction. The buckets are released from rest and begin to move. If the larger bucket is a distance ?0=2.05 m above the ground when it is released, with what speed ? will it hit the ground?
