An object moves with `5ms^(-1)` toward right while the mirror moves with `1ms^(-1)` toward the left as shown in Figure. Find the velocity of image.

Text Solution

Verified by Experts

Take `rarr` as + direction `v_(i) - v(m) = v_(m) - v_(0)`
`v_(i) - (-1) = (-1) - 5`
`:. V_(i) = 7m//s`
`rArr 7m//s` and direction towards left.
