4. Car A is standing at red traffic light. Just as the light turns green car B travelling at a constant velocity of 14 m. s- passes car A, which accelerates uniformly at 2.5 ms-2 to a velocity of 18 m. s-1 and then
travels at a constant velocity.

4.2 How long does it take car A to reach a velocity of 18 m. s-1

4.3 Which car is ahead and by how much, when car A reaches a velocity of 18 m. s-1

4.4 How long does it take for the cars to draw level?
