Question

To a stationary man rain is falling on his back with
a velocity 6 km/h at an angle 30° with vertical. To
make the rain velocity appear vertical the man
should move​

Answer 1

Hii Dear,

◆ Answer -

Vm = 3 kmph

● Explanation -

Given that the rain falls at velocity of 6 kmph at 30° to the vertical.

For this rain velocity to appear vertical, man have to run at horizontal component of this velocity.

Vm = Vr.sinθ

Vm = 6 × sin30°

Vm = 6 × 0.5

Vm = 3 kmph

Therefore, the man have to run at 3 kmph so that rain velocity will appear vertical.

Thanks dear...
