A cord is wrapped around the rim of a solid uniform wheel 0.200 m in radius and of mass 7.20 kg. A steady horizontal pull of 30.0 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. Express your answer in radians per second squared. ? lal = 17.14 rad/s Part B Compute the acceleration of the part of the cord that has already been pulled off the wheel. Express your answer in radians per second squared. VO AE ? lal = m/s? • Part C Find the magnitude of the force that the ade exerts on the wheel. Express your answer in newtons. vO AE F=
