Hi, I was given the following question:
Q: A body starts moving with an acceleration a=const. After a time t it has covered the distance \Delta x[/itex]. What is its speed at time t?<br /> <br /> Answer: \frac{2\Delta x}{t}<br /> <br /> Can somebody say how to arrive at this answer (both mathematically and intuitionally)? I know that \Delta x/twould be the speed w/o acceleration, so the "2" must come from acceleration, but where does it come from?<br /> <br /> Can the answer be obtained from the formula v=v_0+at^2?<br /> <br /> - Kamataat
