Hi, I was given the following question:(adsbygoogle = window.adsbygoogle || []).push({});

Q: A body starts moving with an acceleration [itex]a=const[/itex]. After a time [itex]t[/itex] it has covered the distance [tex]\Delta x[/itex]. What is its speed at time [itex]t[/itex]?

Answer: [tex]\frac{2\Delta x}{t}[/tex]

Can somebody say how to arrive at this answer (both mathematically and intuitionally)? I know that [itex]\Delta x/t[/tex] would be the speed w/o acceleration, so the "2" must come from acceleration, but where does it come from?

Can the answer be obtained from the formula [itex]v=v_0+at^2[/itex]?
