A car of mass 1500 kg is towing a trailer of mass \(m\) kg along a straight horizontal road. The car and the trailer are connected by a tow-bar which is horizontal, light and rigid. There is a resistance force of \(F\) N on the car and a resistance force of 200 N on the trailer. The driving force of the car’s engine is 3200 N, the acceleration of the car is 1.25 m/s\(^2\) and the tension in the tow-bar is 300 N.

Find the value of \(m\) and the value of \(F\).
