Raindrops are falling vertically at a speed of 120 km/h through air that is moving horizontally at a speed of 40 km/h(i.e. the wind is 40 km/h). At what angle do the drops strike the ground?
Air is moving horizontally with 40 km/h speed
Horizontal velocity vector of Air is shown in figure.
Velocity Vector of Raindrops is vertically downward .
Let resulting Velocity of Raindrops makes angle
Hence Raindrops makes angle
