Find the answers to this problem (given in class):

If Dylan stands on top of the CD building, which is 45 feet high, and tosses a ball up into the
air, hoping to temporarily stun Prof. Joyner walking towards the building with a stack of College
Algebra quizzes in order to delay the quiz, how long will it take the ball to come in contact with
Prof. Joyner's head? Prof. Joyner's head is 5 feet off the ground (he is looking down!). The ball is
5 feet above the level of the top of the CD building when it leaves Dylan's hand. Dylan tosses the
ball up at an initial velocity of 15 feet per second.

Additional question: If Dylan misses, how long does it take the ball to hit the ground?
