A car is travelling due east along a straight road when it passes a point P. The Acceleration of the car during the next 7 seconds is modelled in the acceleration time graph above, where a ms-2is the acceleration of the car due east and t secondsis the time after passing the point P.i. Explain why the speed of the car is greatest when t = 6. [1]The speed of the car when it passes P is 12 ms-1.ii. Calculate the speed of the car when t = 3. [3]iii. Show that, when t = 5, the speed of the car is 25 ms-1. [3]iv. Show that, for 5 ≤ t ≤ 7, the acceleration is given by a = -5t + 30. [2]v. Explain how the graph may be used to show that the speeds at t = 5 and t = 7are equal.
