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?
