Physics
A cord is wrapped around the rim of a solid uniform wheel 0.280 m in radius and of mass 9.60 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 wheel
part B
compute the acceleration of the part of the cord that has already been pulled off the wheel
Part C
Find the magnitude of the force that the axle exerts on the wheel
Part D
Find the direction of the force that the axle exerts on the wheel
Part E
Which of the answers in parts A, B, C, and D would change if the pull were upward instead of horizontal
