![Car A is travelling along a straight line with a velocity of 100 km/h. Car B travels at a speed of 50 km/h along a circular path with a radius of curvature of 20 m. As shown in Figure Q3, the speed of car A is increasing at a rate of 20 km/h2 and the speed of car B is reducing at a rate of 10 km/h2. Fig. Q3 Diagram of the two-car problem. (i) Determine the velocity of the car B as measured by the observer A. [5 marks] (ii) Determine the acceleration of the car B as measured by the observer A. [5 marks] (iii) Determine the velocity of the car A as measured by the observer B. [5 marks] (iv) Determine the acceleration of the car A as measured by the observer B.
