Question

Problem 7: The 800-kg car at B is connected to the 350-kg car at A by spring coupling. Determine the stretch in the spring if (a) the wheels of both cars are free to roll and (b) the brakes are applied to all four wheels of B, causing the wheels to skid. Take (Î¼) = 0.4. Neglect the mass of the wheels.
