In one experiment you dropped a ball from a series of increasing heights (recorded in cm) and recorded the time (in seconds) it took for the ball to drop that height. You then plotted the height y vs t2. From that line you calculated the acceleration due to gravity. If the equation of that line was y = 472t2-0.1, and the uncertainty in the slope is 9 cm/s2 and the uncertainty in the y intercept is 0.4 cm, what is...
