In an amusement park,a car rolls on a track as shown below. Find the speed (in m/s) of the car at A, B, and C. Note that the work done by the rolling friction is zero since the point at which the rolling friction acts on the tires ismomentarily at rest and therefore has a zero displacement.V= 0B36 m26 mA13 mm/sm/sm/sVC=Il
