1.	A man moving with 5m//sobserves rain falling vertically at the rate of 10m//s . Find the speed and direction of the rain with respect to ground .
Answer» Solution :`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`
