I ended up just differentiating then doing 0.36T^2 - 4.8T = 0 ---> (0.36T^2) / (0.36T) = (4.8t)/ (0.36T) which gave the right answer, but I wanted to know if there was a way to use the quadratic formula and the above equation since that's how the example in the book was done. I guess at this...

Hey, I did part a and b. Although I need a little help with part c.
I know you're supposed to solve for t^2 but I don't know what value to use for acceleration.
I'd use the quadratic formula to solve for t^2, but...
