At time t =, car B is travelling with a velocit of 15 m/s. It immediatel accelerates uniforml and both cars travel a distance of 6 m, where car B overtakes car A. a Draw a velocit time graph showing the motion of the cars from t = until car B overtakes car A. P b Show that car B overtakes car A at t = 3 s. Velocit (ms 1 ) O t (s) c Find the acceleration of car B. 15 The line = intersects the curve = at two points. Find the -coordinates for each of these two points. Give our answers correct to 2 decimal places. [4 marks] 5
