An object undergoes constant acceleration, initially at rest, then it travels 5 meters in the first second. What additional distance will be covered in the next second?
The Attempt at a Solution
Is it right that it covers 15 meters the next second? I think it should cover 10 meters the next second. Well, if I use kinematic equation to find out the acceleration, a=10m/s^2 when time lasts two seconds, but i think the question asks you the next second, so it lasts only 1 second,too despite it's the 2nd second, so I use my common sense, the acceleration for next second should be 5m/s^2, too. I got the additional distance is 10 meters. Which one is right?
