A car is towing a carriage ulong a straight horizontal road by means of a tow-bar. The mass of the car is 1400 kg and the mass of the carriage is 700 kg. The non-gravitational resistances to the motion of the car and the carriage are 630 N and 280 N respectively. Given that when the car and the carriage are moving at 6 m s', the engine is working at 14.28 kW, find (a) (b) 7. the acceleration of the car, the tension in the tow-bar. When the car and the carriage are moving at 12 m s', the tow-bar suddenly disconnects. Assuming that the power of the engine and the resistances are unchanged, find (c) (d) the new accelation of the car, the time taken by the carriage to come to rest. (Take g as 10 m s*)
