The mine car and its contents have a total mass of 6 Mp and a center of gravity at G If the coefficient of static friction between the wheels and the tracks is µs = 0.4 when the wheels are locked, find the normal force acting on the front wheels at B and the rear wheels at A when the brakes at both A and B are kicked. Does the car move?
