I get what you mean.
It's a little bit to hard for me to describe and i don't have enough time to work on it anymore so I discard my previous post and this topic will be made unrelevant using a different title. Thanks for your potential help anyway. :)
There are two ways to solve this problem(for finding your drop hight). As you know v = g*t in this case so that is the first way to determine your hight. If you want to incalculate the airresistance too you have to get some more badass equations which I do not suggest. Still, to calculate the...
The best way would be to define your relative speed first which is 20 kmh. So you are already catching up with him. The distance to travel would be 28.0 m just like you said. 20 kmh = 5.55 m/s. Because you are already driving at a certain speed and you are accelerating you have to combine some...
I think that is what he wants to know. I remember reading in a physics book once that there are situations where you can say the force is equal to the mass times the velocity.
