Fig. 1.1 presents the speed-time graph for a car’s motion.
The car has a mass of 1200 kg.
(a(i))[2]
Calculate the distance covered by the car in the first 20 s of the motion.
(a(ii))[2]
Calculate the car’s acceleration during the first 20 s of the motion.
(a(iii))[2]
Calculate the resultant force on the car during the first 20 s of the motion.
(b)[1]
Describe how the car moves from 25 s to 40 s.
