throws a ball upwards at an initial velocity of 1.2m/s. The ball was left to drop to the ground but another person was able to catch the ball 20meters below the rooftop. a) Determine the time from when the ball is thrown upwards until it was caught by the second person. b) How high did the ball reach when it was thrown upwards (measured from the rooftop)? c) Assuming that nobody intervened with the drop of the ball, what might be its velocity after 10secs?
