Instantaneous velocity = Instantaneous Rate of Change (IROC) = Derivative
Find s'(t) using the Power rule.
Evaluate s'(1), s'(5), s'(10) and s'(100).
Note: t = 100 seconds is a very long time for a ball to be in motion. (This must be an unearthly situation!) Is s(t) increasing, decreasing or neither as t→∞? Is s(t) changing rapidly or not so rapidly? Explain.
Does a square root function (such as s(t)) have a horizontal asymptote as t→∞?
