in the figure a rope is wrapped around a wheel of radius R= 2.0 m. the moment of inertia if the wheel is 54 kg•m^2. the wheel is mounted with frictionless bearings on an axle through its center. A block of mass 14 kg is suspended from the end of the rope. when the system is released from rest it is observed that the block descends 10 m in 2.0 sec. what is the speed of the block?

A cord is wrapped around the rim of a solid uniform wheel 0.220 mm in radius and of mass 7.60 kgkg. A steady horizontal pull of 40.0 NN to the right is exerted on the cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearings on a horizontal axle through its center. 1. Compute the angular acceleration of the wheel. 2. Compute the acceleration of the part of the cord that has already been pulled...

A bucket of water of mass 15.9 kg is suspended by a rope wrapped around a windlass, that is a solid cylinder with diameter 0.350 m with mass 12.4 kg . The cylinder pivots on a frictionless axle through its center. The bucket is released from rest at the top of a well and falls a distance 10.2 m to the water. You can ignore the weight of the rope. Part A What is the tension in the rope while...

A wheel has a horizontal axis and a moment of inertia I = 220.0 kg۰m2. A rope is wrapped around the rim of the wheel, R = 0.230 m, and the free end of the rope has a 4.00 kg mass attached to it. The system is released from rest. Draw free-body diagrams for both the wheel and the 4.00 kg mass. Determine the angular acceleration α of the wheel.

A wheel (disk) of radius 0.2 m and mass 1 kg are mounted on a frictionless horizontal axis. A massless cord is wrapped around the wheel and attached to a 2 kg object that slides on a frictionless surface inclined at an angle of 60 degrees with the horizontal. What is the acceleration of the block as well as the angular acceleration of the wheel about its axis of rotation? Answer: 6.93 m/s^2, 34.64 rad/s^2

A block of mass m = 2.5 kg is attached to a string that is wrapped around the circumference of a wheel of radius R = 8.8 cm . The wheel rotates freely about its axis and the string wraps around its circumference without slipping. Initially the wheel rotates with an angular speed ω, causing the block to rise with a linear speed v = 0.42 m/s A) Find the moment of inertia of the wheel if the block rises...

A uniform spherical shell of mass M = 17.0 kg and radius R = 0.310 m can rotate about a vertical axis on frictionless bearings (see the figure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I = 0.210 kg·m2 and radius r = 0.100 m, and is attached to a small object of mass m = 1.50 kg. There is no friction on the pulley's axle; the cord does not slip...
