Solution:
Velocity of Rain = - V j
Velocity of Person = V i
Velocity of Rain with respect to the Person = - V i - V j
so, V√2 = 10 ⇒ V = 5√2 km/hr
Rain drops are falling vertically and a man is running on the ground horizontally with speed equal to the rain with respect to the ground. Rain drops appears to him hitting with velocity 10 km/hr. Find velocity of rain.
