A car of mass 1000kg is driven onto along ice plank of mass 200kg lying on a level, icy road at a speed of 36km/hr. The wheels are blocked(they stop running) by an abrupt braking. The friction coefficient between the ice and the wheels is 0.2 and 0.1 between the ice plank and the icy road. After how much time will the car stop with reference to the ground? What distance will it cover until then?
