    A 1600 kg car moves along a horizontal road at speed v0 = 18.8 m/s. The road is wet, so the static friction coefficient between the tires and the road is only µs = 0.321 and the kinetic friction coefficient is even lower, µk = 0.2247. The acceleration of gravity is 9.8 m/s 2 . Assume: No aerodynamic forces; g =9.8 m/s forward is the positive... show more
