1. The problem statement, all variables and given/known data While driving north at 25 m/s during a rainstorm you notice that the rain makes an angle of 38 degrees with the vertical. While driving back home moments later at the same speed but in the opposite direction, you see that the rain is falling straight down. From these observations, determine the speed of the raindrops relative to the ground. From these observations, determine the angle of the raindrops relative to the ground. 2. Relevant equations None given 3. The attempt at a solution I believe I am misunderstanding the wording of the question. I thought that since the rain drops are falling vertical while you are driving south at 25 m/s, it must mean that the rain drops are traveling 25 m/s in the direction that the car is traveling. I am at a loss of where to start. I know that 25 m/s is the wrong answer to the first question. Any ideas?
