It's true that the v_drop/earth (using your notation here) is vertical before the drops reach the side window. However, when they are on the side window and have "acquired" the horizontal velocity of the car while the car is moving, doesn't v_drop/earth now have a horizontal component as well...

Okay, so I have two texts here, with similar questions. I shall quote one of the texts, and try to show you which parts confuse me, and why. I'm almost certain I haven't understood reference frames properly. Problem: "A car travels due east with a speed of 50.0km/h. Rain-drops are falling at a...

Wouldn't this mean that the drops are not traveling at the same horizontal velocity as the car? The problem I was doing in the textbook said that we are to assume they are traveling at the same horizontal velocity as the car. I think this is more a question of relative motion than of...

Once the rain is on the window, it is moving at the same speed as the car. If the car is moving at 60mph, then the rain is also moving at 60mph. The 60mph of the car was measured with respect to the ground, so it should be the same for the rain. So how can it be that the horizontal velocity of...

The problem assumes that there is no air resistance. Apologies for not mentioning that. If the car was moving at a constant velocity, and a vertical piece of string, say, hangs from the roof of the car, the string would stay vertical. It would not be slanted. I just can't bring myself to...

Initially, the rain would not have a horizontal component. Once it is "on the car," the horizontal velocity of the rain relative to the rain would be the same as that of the car relative to the ground. This would mean that the horizontal velocity of the rain relative to the car is zero. I know I...

I recently solved a question related to the problem below, but am having trouble getting an intuition for the problem. Suppose an automobile is traveling at a constant horizontal velocity, u, and it's raining. There is no wind, so the raindrops do not have an initial horizontal velocity, just...
