Figure 19.45 9.45 .. CP A thin, light wire is wrapped around the rim of a wheel (Fig. E9.45). The wheel rotates without friction about a stationary horizontal axis that passes through the center of the wheel. The wheel is a uniform disk with radius R = 0.280 m. An object of mass m = 4.20 kg is suspended from the free end of the wire. The system is released from rest and the suspended object descends with constant accel- eration. If the suspended object moves downward a distance of 3.00 min 2.00 s, what is the mass of the wheel?
