Physics - Rotation Question with Solution | TestHub

A wheel A is connected to a second wheel B by means of inextensible string, passing over a pulley C , which rotates about a fixed horizontal axle O , as shown in figure. The system is released from rest. The wheel A rolls down the inclined plane OK thus pulling up the wheel B which rolls along the inclined plane ON . Determine the velocity (in $\mathrm{m}/\mathrm{s}$ ) of the axle of the wheel A, when it has travelled a distance $\mathrm{s}=3.5\mathrm{m}$ down the slope. Both wheels and the pulley are assumed to be homogeneous disks of identical weight and radius. Neglect the weight of the string.
