A car in a highway is accelerated uniformly from rest with an acceleration of 4m/s for 4 seconds. Then it maintains its velocity for 6 seconds. Finally it is brought to rest at a road junction with uniform deceleration in another 3 seconds. (i) What is the velocity of the car just after the first 4 seconds? (ii) What is the deceleration during the last 3 seconds? (5 marks) (5 marks) (iii) By sketching a velocity-time graph, find the total distance travelled by the car. (5 marks)
