Identify the intervals where the acceleration is positive. Consider only the intervals [0, 10], [10, 20], [20, 30], [30, 40],
and [40, 50].
(Give your answer as an interval in the form (*,*). Use the symbol ∞ for infinity, U for combining intervals, and an appropriate
type of parenthesis "(",")", "[","]" depending on whether the interval is open or closed. Enter Ø if the interval is empty. Express
numbers in exact form. Use symbolic notation and fractions where needed.)
