Question

Rain is falling down at 4 km/h and man running at3km/h then vel of rain falling on man

Answer 1

Answer:

Explanation:

Velocity with which rain will fall on man will be resultant velocity so the rain will appear slant to the man.

Velocity:-

(4)^2 + (3)^2 = V^2

V^2 = 16+9

V^2=25

V=5Km/hr

Answer 2

Answer:

Velocity of ran falling on man=

$\sqrt{ {x}^{2} + { {y}^{2} }^{2} + 2xy} \\ = \sqrt{ {3}^{2} + {4}^{2} + 2 \times 3 \times 4} \\ = \sqrt{9 + 16 + 24} \\ = \sqrt{49} \\ = 7$

Velocity of ran on man is 7 kmph.

It is in slant direction.
