Question

1. Two cars 'A' & 'B' are moving in the same directions with different. velocities 4omls & 25 mls respectively from the same place at the same time-calculate the relative velocity of "A with respect to 'B' Also calculate distance between. them after 2 seconds. ​

Answer 1

Velocity of car A is 40 m/s

Velocity of car B is 25m/s

We Know that

Relative velocity of car A with respect to car B

VA-VB

40m/s-25m/s

15 m/s

Now

Distance travelled by them in 2sec is

VA×t

15m/s×2sec

30m
