In university i visit a physic course, just for "fun".
Now i got some tasks to do, but i dont know how.
Maybe you guys can help me out there

Task 1:
A jumbojet needs a speed of 360 km/h to get up in the air.
How high is the lowest average acceleration so that he can start on a 1,8 KM long street?

Task 2:
If a car could reach an acceleration of 50m/s², how long would it take to get from 0 to 100 km/h ?

Task 3:
A car needs to come from 150 km/h to 80 km/h within 800 meters.
What's the lowest average negative acceleration ?

Thanks in advance

Are you asking for help with a college physics course that you sat in? or are you actually enrolled in the class?

All of these are fairly simple story problems, if you're having a difficult time with the terms i suggest you get a basic physics text book and do some general reading on the subject.

got it solved, thanks for all the hate

wrong forum, reported

Science, Technology and Nature --> Physic is no Science, clever boy

this is a subforum designed to discuss science, not science homework. ALL homework questions should be posted in the homework hotline subforum by design, so he is right and you are wrong even though you got your answer.

alot of detectives around in this nerd room

it was actually an attempt to steer you to the right subforum. homework hotline gets alot more traffic than the science subforum, mainly due to the fact that some people pay for help. The science forum gets mostly conspiracy theories and space exploration talk, there isn't much hard science.

Perhaps you are the one being defensive when people are only trying to help you get help.

oh okay, so reporting my topic AND posting it for no reason = trying to help me?
I won't ask for help again here, this is just a redic. forum
