A wheel with radius 0.4m is mounted on an axle and is free to rotate. Beginning with the wheel at rest, a string wrapped around the edge of the wheel, is pulled with a force of 20 N . While the string is unwinding the wheel rotates through an angle of 10 rad . If the angular speed of the wheel after the string is pulled is 4 rad/s , what is the moment of inertia of the wheel?
A bicycle wheel is mounted on a fixed, frictionless axle, with alight string wound around its rim. The wheel has moment of inertia I=kmr2, where m is its mass, r is its radius, and k is a dimensionless constant between zero and one. The wheel is rotating counterclockwise with angular velocity w0, when at time t=0 someone starts pulling the string with a force of magnitude F. Assume that the string does not slip on the wheel.Part ASuppose that after a certain time tL,...
A wheel with mass of 5 kg and a radius of 15 cm is mounted so that it spins on an axle through its center. A light-weight string is wound around the circumference of the wheel. If a constant force of 3.0 N is applied to the end of the string for 1.0 seconds, what will be the change in the angular velocity? (Model the wheel as though it were a uniform cylinder.)
A cord s wrapped around the rim of a solid uniform wheel 0.22 m in radius and of mass 8.60 kg . A steady horizontal pull of 50.0 N 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. Part A Compute the angular acceleration of the wheelPart B Compute the angular acceleration of the part of the cord that has already been pulled...

A uniform-density wheel of mass 10 kg and radius 0.33 m rotates on a low-friction axle. Starting from rest, a string wrapped around the edge exerts a constant force of 15 N for 0.81 s. (a) What is the final angular speed? 0r = 7.36 radians/s (b) What was the average angular speed? T2.98 average = radians/s (c) Through how big an angle did the wheel turn? -12.41 . radians/s (d) How much string came off the...
In

frictionless horizontal axle. A massless cord is wrapped around the
wheel and attached to a 2.0 kg box that slides on a frictionless
surface inclined at angle θ = 25° with the horizontal. The
box accelerates down the surface at 2.1 m/s2. What is
the rotational inertia of the wheel about the axle?

In the figure, a very light rope is wrapped around a wheel o radius R = 2.0 m and does not slip. 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 s. What is the moment of Inertia of the wheel?
A bike wheel with radius 0.500 m is mounted on a stationary stand and is free to rotate. A constant force of 16.0 N is applied tangent to the rim. What is the resulting angular acceleration of the wheel? (The wheel's moment of inertia is 0.625 kg m2.) O 25.6 rad 00 O 12.8 rad O 17.5 rad o o
A light string is wrapped
around the outside of a 2.0-kg-wheel whose radius is 75 cm. The
wheel has a frictionless axel that allows it to rotate but prevents
its center of mass from moving. Assume the moment of inertia of the
wheel is the same as that of a point particle of equal mass at the
same radius from the axel. The string is then attached to a 3.0-kg
hanging mass that is released from rest. While the mass...
A light rope is wrapped several times around a large wheel with a radius of 0.395 m. The wheel rotates in frictionless bearings about a stationary horizontal axis, as shown in the figure (Figure 1). The free end of the rope is tied to a suitcase with a mass of 16.5 kg. The suitcase is released from rest at a height of 4.00 m above the ground. The suitcase has a speed of 3.00 m/s when it reaches the ground....
