Rain falls vertically downwards at 4m/s. if wind blows at 5m/s towards south. find the direction and the velocity of the rainfall |
|
Answer» Velocity of wind will be added to velocity of RAIN Velocity of rain Vr=4(−j^) m/s Velocity of wind Vw=3(i^) m/s Net velocity V=Vr+Vw =3i^+(−4j^) angle from vertical will be θ=tan−1∣−4∣3=37o. |
