Question

the velocity time graph of car A and B which start from same place and along a straight road in same direction is shown below. 



(a)the distance travelled by two cars A and B in 8sec.

(b) which of the two cars is ahead of after 8sec and by how much?

Answer 1

(a)
Distance = v/t
In 8 sec
80/8=10m

Answer 2

heya...

here is your answer..

a)
speed/velocity = distance/ time

therefore. distance = velocity/ time..

distance travelled by Car A (in 8 second) = 80m/s / 8 s

= 10 m..

distance travelled by Car B (in 8 second)=
60/8

= 7.5 m

b)
Car A is ahead of Car B by 10-7.5
that is by 2.5 m...


hope helped..
