A car with vertical windshield moves in a rainstorm at a speed of . The rain drops fall vertically with a constant speed of . The angle at which raindrops strike the windshield is:
Step 1: Given
Speed of the car,
Speed of the raindrop,
Step 2: Draw the free body diagram
Step 3: Determine the angle
The resultant angle is given by,
Therefore, the raindrop will strike the windshield at an angle of .
