Understanding of physics?
Hello,
At school, we're studying uniformly accelerated motion. We were given assignments on the subject, and one of the assignments was (quoted 1 to 1): "A car accelerates from 30 km/h to 70 km/h in 15 seconds. What distance does the car travel during this acceleration?"
I know what I have to do, etc., etc., and calculate the distance traveled during acceleration. BUT: the teacher told us to calculate the entire distance, including the distance traveled at 40 km/h, which I find illogical because it's not even asked.
Please enlighten me 🙏

I think the sketch will be misunderstood. If you write in the sketch “Climbing during acceleration” and “before”, this is not correct. If the car were to travel constant at 30km/h, the distance corresponding to the blue surface would be covered during the 15s. Accelerates from 30 to 70km/h in addition the distance corresponding to the purple surface.
Thank you. So it makes much more sense 🙂
You probably calculated only the purple area with the standard formula, i.e. you expected it to accelerate from the stand in 15s to 40 km/h.
If it is, you have to add the blue area to it.
Right, thank you very much:)
The word “translated” does not exist in the German language.
I do not recognize any relation between the task and this speed.
typos don’t exist in your world but thank you
