Dean collected data for the Free Fall Motion lab by himself and tested multiple heights. When he plotted his velocity vs time data, he tried to fit it with both a linear and a quadratic model. 475 425 y = -1406.6x2 + 1956.4x - 163.35 375 325 y = 1100.2x - 48.585 Velocity (cm/s) 275 225 175 125 0.15 0.25 0.35 0.45 0.55 Time (s) 1) Which line is the linear model? Rewrite the equation in terms of velocity (v) and time (t) instead of x and y. 2) Which line is the quadratic model? Rewrite the equation in terms of velocity (v) and time (t) instead of x and y
