  A baggage tractor pulling luggage carts from an   airplane. The tractor has mass 6500 kg while  cart A has mass 2500 kg and cart B has mass  150 kg. The driving force acting for a brief  period of time accelerates the system from rest  and acts for 3s. (a) If this driving force is given  by F=820N. find the speed after 3s (b)  Wat is the horizontal force acting on the  conneting cable between the tractor and cart  A   at this instant
