You want to figure out the friction that acts on the rear wheel of your bike. you give the wheel a quick push and find that it spins 2 complete revolutions in the first second and takes 60.0 seconds to come to rest. (a) if the wheel has a mass 0.15 kg and a radius of 0.35 m, what is the moment of inertia, assuming all the mass is located at the radius? (b) if the frictional torque is constant, estimate the value of this torque? (c) what is theradial acceleration of a point on the tire? (d) how many revolutions did the wheel make before coming to rest? ?
