A car goes up a hill and down the other side. The time it takes the car is 3.25 minutes (it starts at 0).
The V(t) = .5t^2 -1.5t mi/min
What was the minimum velocity in mph?
When did it reach the top of the hill?
How would I find these?.. I know how to work with them, I am just not sure on what I am looking for.
