10. (a) Consider a situation in which a car overtakes a lorry on a narrow road. Explain qualitatively why the car might be pulled sideways during the overtaking manoeu- vre, and whether it would be pulled towards or away from the lorry. [3 marks) (b) To extinguish a fire on the 10th floor of the Llandinam Tower, water must be pumped 25m from ground level through a hose of diameter 6cm. The water leaves the hose through a nozzle of diameter 4cm at a speed of 10m/s. How much higher is the water pressure at ground level than when it leaves the nozzle? [7 marks] (You should take g = 10m/s and leave your answer in terms of p, the density of the water.)
