i) ii) b) The figure shows a lorry of mass 1600 kg towing a car of mass 900 kg along a straight horizontal road. The two vehicles are joined by a light towbar which is an angle of 15 to the road. The lorry and the car experience constant resistances to motion of magnitude 600N and 300N respectively. The lorry's engine produces a constant horizontal force on the lorry of magnitude 1500N. Find: iv) 15 the acceleration of the vehicles (3 marks) (4 marks) the tension in the towbar When the speed of the vehicles is 6 m/s, the towbar breaks. Assuming that the resistance to the motion of the car remains of constant magnitude 300N: iii) Find the distance moved by the car from the moment the towbar breaks to the moment when the car comes to rest. (4 marks) State whether, when the towbar breaks, the normal reaction of the road on the car is increased, decreased or remains constant. Give a reason for your answer.
