Differentiate and equate to zero, get t=3.5, sub this back in and get a speed of 4.5. Next, since you know the curve is shaped like a parabola, the max speed will either be this minimum point or either side of the boundary, so you need to find v when t is 0 and 4 and deduce which one is biggestSo you differentiate the eq for v to get acceleration and equate it to 0 right?
