45° 1 1 I 1 P = 120m 25 km/h 70 km/h в | Figure Q3 (b)
(b) A car A travelling at the speed of 25 km/h while a car B travelling at the speed of 70 km/h as shown in Figure Q3 (b). The car B is accelerating at 1100 km/h? while car A maintain a constant speed as currently displayed. Considering the aforementioned factors, (1) Find the magnitude and direction of velocity of car A with respect to car B, VA/B, (6 marks) (ii) Determine the magnitude and direction of acceleration of car A relative to car B, A/B (6 marks)
