The diagram shows part of a journey by a truck.

(a) The truck accelerates from rest to 18 m/s in 30 seconds.
Calculate the acceleration of the truck.




Answer(a) m/s2 [1]


(b) The truck then slows down in 10 seconds for some road works and travels through the road
works at 12 m/s.
At the end of the road works it accelerates back to a speed of 18 m/s in 10 seconds.
Find the total distance travelled by the truck in the 100 seconds.




Answer(b) m [3]
