A man is walking on a road with a velocity \(3 \mathrm{kmsh}^{-1}\). Suddenly rain starts falling. The velocity of rain is \(10 \mathrm{kmoh}^{-1}\) in vertically downward direction. The relative velocity of the rain w.r.t. man is
- \(\sqrt{7} \mathrm{knh}^{-1}\)
- \(\sqrt{13} \mathrm{kmh}^{-1}\)
- \(13 \mathrm{kmh}^{-1}\)
- \(\sqrt{109} \mathrm{mmh}^{-1}\)
Answer
(D) 109 mmh ^ -1
