Question

Two cars moving in opposite direction cover some distance 'd' in one hour. If the cars were moving in north-south direction, what will be their displacement in one hour?

Answer 1

I think d.

Answer 2

how?

Answer 3

2d

Answer 4

2d because one moves south 1d and the other moves north 1d

Answer 5

d because displacement is 'the difference between the path of the initial and final position covered by a moving object'

Answer 6

in this question the distance and displacement is the same, as the opposite direction can be said equal to as north-south direction. The two cars covers distance of d in an hour. Therefore the displacement will be d for each for the car assuming the initial position is same.

Answer 7

in this question the distance covered in one hour is d ,but since they are in the opposite direction, the displacement of one car is the negative of the other .they cancel each other out and the total displacement is 0.

Answer 8

i am confused as i got three different answers from u all. Bt still thanx
