A girl standing on road holds her umbrella at 45° with the vertical to keep the rain away. If she starts running without umbrella with a speed of 152kmh-1, the rain drops hit her head vertically. The speed of rain drops with respect to the moving girl is :

V=tanθ=VGVRG⇒1=VGVRG⇒152=VRG

V=tanθ=VGVRG⇒1=VGVRG⇒152=VRG
