i want to get to a speed in a specified time.

I'm stupid and seriously can not find this anywhere so either I just suck at using google or this is a complicated answer

I have a car, I want it to reach from 0 speed to 50 speed in 5 seconds.

I then want to be able to change the time in seconds it should take to get to max speed, and change the maximum speed it should have reached after that time.

everywhere I search it comes up with the speed, distance, time formula. I know speed, distance, time but it isn't what I need, since I don't know what distance it will have ended up traveling and I don't care what distance it travels I just care about the speed.

I just want a way to get from 0 to maxSpeed in timeItShouldTake.

brain really isn't working at the moment so any help is really appreciated! thank you
