The following equation is one of the equations for uniformly accelerated motion. $s = ut + \frac{1}{2}at^2$ The apparatus is set up to measure the time $t$ for a marble to pass between two light gates linked to timers. Before being released, the marble is held against the stop. The vertical separation $s$ between the light gates is measured. Which graph does not represent the correct relationship when light gate 2 is raised towards light gate 1, which remains fixed?
