Quizplus · Accepted Answer

When the rain makes slanted 45° streaks on the side windows of a moving car, it indicates that the horizontal component of the rain's velocity (due to the car's motion) is equal to the vertical component of the rain's velocity (due to gravity). This means the speed of the car equals the speed of the falling drops.
