A cord is wrapped around a wheel of diameter 1.0 ft. If the cord is pulled down 3.0 ft, how many revolutions has the wheel rotated?
A.) 6.0 rev
B.) 0.95 rev
C.) 3.0 rev
D.) 38 rev
Homework Answers
it take 2pir distance when one revolution is completed
L = 2pir*n
=> 3 = 2pi*0.5*n
=> n = 0.95 rev
option B

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.

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.

(a) A rope is wrapped tightly around a wheel with a radius of 3 feet. If the radius of the wheel is increased by 3 feet to a radius of 6 feet, by how much must the rope be lengthened to fit around the wheel? (Round your answer to two decimal places.) ft (b) Consider a rope wrapped around the Earth's equator. The radius of the Earth is about 4000 miles. That is 21,120,000 feet.

The cable lifting an elevator is wrapped around a 1.0-m-diameter cylinder that is turned by the elevator's motor. The elevator is moving upward at a speed of 1.7 m/s . It then slows to a stop, while the cylinder turns one complete revolution. How long does it take for the elevator to stop? Express your answer to two significant figures and include the appropriate units. Thanks for the help!

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...
