What is a cars final speed after accelerating for four seconds if everything else in the problem remained the same what would the speed have been after three seconds?

This will varry depending on car weight and size of engine and amount of traction and road surface and reaction time of driver allong with weater conditons of humitidy and barametric pressure that have factors on how well the engine will run.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
