Acord is wrapped around the rim of a wheel 0.235 m in radius, and a steady pull of 43.0 n is exerted on the cord. the wheel is mounted on frictionless bearings on a horizontal shaft through its center.
the moment of inertia of the wheel about this shaft is 5.15 kg⋅m2 compute the angular acceleration of the wheel.

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
