Alex climbs to the top of a tall tree while his friend Gary waits on the ground below. Gary throws a ball up to Alex, who allows the ball to go past him before catching the ball on its way down. The ball has an initial speed of 10 m/s and is caught 4.5 m above where it was thrown. Ignoring the effects of air resistance, how much time t passes between the moment Gary throws the ball and the moment Alex catches it? t= 6.69 Incorrect
