A man moving with `5 ms^-1` observes rain falling vertically at the rate of `10 m s^-1`. Find the speed and direction of the rain with respect to ground.

Text Solution

Verified by Experts

`V_(RM)=10m//s`,
`V_(M)=5m//s`
`vecV_(RM)=vecV_(Ru)-vecV_(M)`
`rArr vecV_(Ru)=V(rm)-vecV_(M)rArr vecV_(R)=5sqrt5`
`tantheta=1/2, theta ="tan"^(-1)1/2`
