The wheel consists of a 4-kg rim of 250-mm radius with hub and spokes of negligible mass. the wheel is mounted on the 3-kg yoke OA with mass centered at G and with radius of gyration about O of 350 mm. If the assembly is released from rest in the horizontal position and if the wheel rolls on the circular surface without slipping compute the velocity at point A when it reaches A'. Treat the wheel as a uniform solid disk (moment of inertia of the wheel = 1/2mr^2).
