A ball is tossed up with some initial velocity. Which of the following statements about ball’s velocity 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 down the ball has negative velocity which magnitude greater than half of the magnitude of its initial velocity At the maximum height (hmax) ball’s velocity is zero. After half the time it takes the ball to get to maximum height has elapsed, the magnitude of the ball’s velocity decreased by a half. At the point half way up to the maximum height (hmax/2) while going up the ball has velocity equal to half of its original velocity. At the original height when falling back the ball has negative velocity which magnitude equal to the magnitude of its initial velocity.
