A 906 kg car is held in place by an unreliable winch. The gearbox of the winch brakes and at that moment the cart - drum system free falls from rest. during the cars fault, there’s no slipping between the rope (massless), the pulley, and the winch drum.

find the speed of the car as it hits the ground. The moment of inertia of the winch drum is 237 kg m^2 and that of the pulley is 30 kg m^2. The radius of the drumis 81 cm and the radius of the pulley is 5 cm and the acceleration due to gravity is 9.81 m/s^2
Answer in units of m/s
