A ball is thrown vertically upward with an unknown initial velocity and from a height of 2 meters above the ground. By measuring its velocity just before hitting the ground it is found to be -15 m / s. a) Determine the value of its initial velocity. b) Determine the maximum height that the ball reaches with respect to the ground. c) How long did it take for the ball to hit the ground?
