a car moving at 10ms-1 was uniformly accelerated until its velocity reaches 20ms-1. it then maintains this speed for another 20s after which the brakes were applied and the vehicle finally brought to rest in a further 10s.
a) draw the velocity-time graph of the motion.
From the graph, determine
i. the acceleration at each stage of the motion
ii. the distance traveled at each stage of the motion
iii. the total stance traveled by the car during the journey

b) determine all the above using the equations of motion?
