A particle moves along a line so tat its position at any time t>= 0 is given by the function
where s is measure in meters and t is measured in seconds
Find the displacement in meters and t is measured in seconds
The book gives this:
The displacement of the object over the time inverval from t to tx (they used delta t but this is easier for the purpose) is
delta S = f(t + tx) - f(t)
I did what I needed, by acting as this is a difference quotient without a limit or denominator, to solve normally and got this:
The answer, however, is 10.
I'm sure there is some reason why the above (as in my answer) = 2t. But, I don't know how.
Thank you!.
