A wheel can be modeled as a thin ring having mass 10 kg and four spokes made of slender rods each of mass 2 kg. the wheel has radius .48 m and is traveling down a 10 degree decline. In addition to its own weight the wheel is supporting a weight of 300 N at its axle. At t = 0 the wheel has a velocity 14 m/s and a moment is applied to slow the wheel.
A) what is the moment required to stop the wheel 50 m downhill from its location at t = 0?
B) what is the minimum coefficient of friction that will allow the wheel to slow to a stop without skidding?
