A particle moves along the x axis. Its position is given by the equation x = 1.90 + 3.10t - 4.15 t2 with x in meters and t in seconds. Determine its position at the instant it changes direction.
When I'm reading this problem I picture a parabola and the instant the particle changes direction is at the maximum. However I'm not sure that is right and am having trouble figuring out how to use the quadratic equation to find the position. I was thinking that when the position changes it goes from positive to negative is that right?
Any help would be greatly appreciated
