Question

A car travels with a uniform velocity of 20 m s-1
for 5 s. The brakes are then applied and the car
is uniformly retarded. It comes to rest in further
8 s. Draw a graph of velocity against time. Use
this graph to find :
(i) the distance travelled in first 5 s,
(ii) the distance travelled after the brakes are
applied,
(iii) total distance travelled, and
(iv) acceleration during the first 5 s and last
8 s.​
