A thin, light wire is wrapped around the rim of a wheel, as shown in the following figure. 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 0.260m . An object of mass 4.30kg is suspended from the free end of the wire. The system is released from rest and the suspended object descends with constant acceleration.(Figure 1)
Part A If the suspended object moves downward a distance of 3.40m in 1.86s , what is the mass of the wheel?
A bicycle wheel has an initial angular velocity of 16 radians/second and acceleraties to a final angular velocity of 42 radians/second, Determine the time required for this motion to occur
