Question

Rain is falling vertically downwards with respect to ground. If a girl running on the ground with speed 3 km/h observes the rain is falling with speed 5 km/h then actual speed of rain is

Answer 1

Let velocity of rain be Vr

and velocity of girl be Vg. Note that Vr and Vg are perpendicular to each other. Let observed velocity of rain be V then.

V² = Vg² + Vr²

5² = 3² + Vr².

Hence Vr = 3 Km/h
