Unformatted text preview: c) As v approaches s m 8 . 9 , the height h becomes infinite, corresponding to a relative velocity at the time the second ball is thrown that approaches zero. If , s m 8 . 9 v the first ball can never catch the second ball. d) As v 0 approaches 4.9 m/s, the height approaches zero. This corresponds to the first ball being closer and closer (on its way down) to the top of the roof when the second ball is released. If , s m 9 . 4 v the first ball will already have passed the roof on the way down before the second ball is released, and the second ball can never catch up....
