Rain is falling vertically at 8.0 ms- relative to the ground. The rain drops make tracks on the side window of a car at an angle of 30° below the horizontal. Calculate the speed of the car.​

Answer»

18° from vertical or 72∘ from horizontally.Explanation:enter image source hereAir is MOVING horizontally with 40 km/h speedHorizontal velocity vector of AIR is SHOWN in figure.Velocity Vector of Raindrops is VERTICALLY downward .Let resulting Velocity of Raindrops makes angle θ from thevertical.Then angletanθ=vHorizontalvvericle=40120=13 θ=tan−1(13)≈18∘ Hence Raindrops makes angle 18∘ from the vertical or make angle 72∘ from Horizontal.Explanation:I I hope this is your answer please mark me brainly
