Question

A man is walking on a road with a vele
3 km/hr. Suddenly rain starts falling. The velocity
of rain is 10 km/hr in vertically downward direction
The relative velocity of the rain is -
​

Answer 1

Answer:

Explanation:

The relative velocity of the rain with respect to to man is-  √109 km per hour (i.e option 3 is the correct answer)

Explanation:

A man is walking on a road with velocity 3km/hr

Suddenly rain starts falling. The velocity of rain is 10km/hr in vertically downward direction.

From the problem,

Let V(man)= Velocity of man = 3km/hr

V(rain) = Velocity of rain= 10km/hr

V(relative) = √V(man)^2+V(rain)^2

putting the values:

               = √(3)^2+(10)^2

              = √9+100

              = √109

hence the relative velocity of the rain with respect to to man is- √109km/hr
