Anoop is moving due east with a velocity of `1 m//s` and Dhyani is moving due west with a velocity of `2 m//s.` what is the velocity of Anoop with respect to Dhyani?

Explanation

It is a one dimensional motion. So, let us choose the east direction as positive and the west as negative. Now given that
`v_(S)` = velocity of Seeta `= 1ms^(-1)`
and `v_(G)` = velocity of Geeta `= -2 ms^(-1)`
Thus, `v_(SG)` = velocity of Seeta with respect to Geeta
`=v_(S)-v_(G)=1-(-2)=3 ms^(-1)`
Hence, velocity of Seeta with respect to Geeta is 3 m/s due east.
