Question

To a stationary Man rain is falling on his back with a velocity of 60 kilometre per hour at an angle 30 degree with vertical to make the rain velocity appear vertical the man should move​

Answer 1

Answer:

Since, the velocity of the rain is 60 km/hr and is falling through an angle of 30degree and thus there will be two components to the velocity of the rain with respect to the man.

One on the horizontal will be 60cos30 as the angle 30 is with the vertical which will be 3√3 and thus the other component will be 60sin30 which will be 3km/hr which will also be the velocity of the man to make the rain fall vertical.

Answer 2

Hii Dear,

◆ Answer -

Vm = 30 kmph

● Explanation -

Given that the rain falls at velocity of 60 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 = 60 × sin30°

Vm = 60 × 0.5

Vm = 30 kmph

Therefore, the man have to run at 30 kmph so that rain velocity will appear vertical.

Thanks dear...
