A truck of mass 10 000 kg pulls a trailer of mass 6 000 kg along a level road. The truck and trailer accelerates at 0.75 m/s^2. Friction and air resistance act on both the truck and trailer. The total drag force is a constant 5 000 N, with a half of this force acting on the trailer. If the trailer lost connection with the truck, what will be the acceleration of the truck?
