Question

rain is falling vertically downwards with a velocity of 3 km/hr. a man walks in the rain with a velocity of 4 km/hr. the raindrops will fall on the man with a velocity of

Answer 1

use hypotenuse theorem

Answer 2

Hey dear,

● Answer-

v = 5 km/hr

● Explaination-

Let vm be velocity of man and vr be that for rain.

Man is walking horizontally and rain is falling vertically, so these two velocities are perpendicular to each other.

Resultant velocity of rain to man is-

v = √(vr^2 + vm^2)

v = √(3^2 + 4^2)

v = √(9 + 16)

v = √(25)

v = 5 km/hr

Therefore, rain will fall down on man with velocity 5 km/hr.

Hope it helps...
