QUESTION TWO: A car is capable of reaching 27 km/h from rest in 4 seconds on a level road against resistances amounting to 4% of the vehicle mass. If the car has a mass of 1200 kg, calculate the minimum distance over which it could reach 36km/h from rest if towing a caravan of mass 700 kg. Assume the tractive effort to be constant and the tractive resistance to be the same rate for car and caravan.
