A student holds a ball 1.55 meters above the ground and drops it. Her friend uses a stopwatch and measures a time of 0.57 seconds for the ball to hit the ground. Since the value for g obtained from the data is inaccurate, one of the measurements must have been incorrect. Assuming the time was exactly accurate, from what height was the ball actually dropped?
