A ball is tossed up with some initial velocity. Which of the following statements about ball’s acceleration along its path are true? Assume no air drag. Consider up as the positive direction. At the point half way up to the maximum height (hmax/2) while going up the ball exhibits acceleration of -10 m/s/s. At the original height when falling back the ball exhibits acceleration of -10 m/s/s. At the point half way up to the maximum height (hmax/2) while going down the ball has negative acceleration of magnitude 5 m/s/s. After half the time it takes the ball to get to maximum height has elapsed, the magnitude of the ball’s acceleration decreased by a half. At the maximum height (hmax) ball’s acceleration is zero.
