A man moving with 5 m/s observes rain falling vertically at the rate of 10 m/s find the speed and direction of the rain with respect to ground .

Text Solution

Verified by Experts

`V_(RM ) = 10 m//s`
`vecV_M = 5 m//s`
` vecV_(RM) = vecV_(Ru) - vecV_(M)`
`implies vecV_(Ru) = V_(rm ) - vecV_M implies vecV_R = 5 sqrt(5)`
` tan theta =(1)/(2) , theta = tan^(-1)"" 1/2`
