Assume it to be approximately an annular ring with an inner radius of r1 = 0.280 m and an outer radius of r2 = 0.440 m. the motorcycle is on its center stand, so that the wheel can spin freely.(a)if the drive chain exerts a force of 2450 n at a radius of 5.00 cm, what is the angular acceleration (in rad/s2) of the wheel?
