 * In all of the following problems you can assume that if the object is reaching maximum range thus being thrown/shot/hit at a 45** o **angle and air friction is ignored.** (See this page to further investigate )


 * 1)** During a cliff dive competition, a diver begins a dive with his center of gravity 70 feet above the water. He jumps up off the cliff with an initial velocity of 8 feet per second. How long after the diver begins his dive does his center of gravity reach the water?


 * 2)** Two softball players are practicing catching fly balls. One player throws a ball to the other. She throws the ball upward from a height of 5.5 feet with an initial velocity of 40 feet per second for her teammate to catch. If her teammate misses the ball and it lands on the ground, how long was the ball in the air?


 * 3)** A water balloon is launched with an initial velocity of 60 feet per second. The balloon is released 3.5 feet off the ground. What is the maximum height of the water balloon?


 * 4)** A cannon ball is shot at an initial velocity of 1769 feet per second. If the cannon is 4 feet off the ground what is the maximum height of the cannon ball?


 * 5) ** Fenway Park is a Major League Baseball Park in Boston, MA for the Boston Red Sox. Fenway offers seats on the top left field wall in what is affectionately known as the "Green Monster". A person sitting in one of these seats accidentally drops his sunglasses on the field. How long does it take for the sunglasses to reach the field?


 * 6)** Now another person sitting in one of these seats accidentally throws the bobblehead downward that she received upon entering Fenway Park on the field with an initial velocity of 10 feet per second. How long does it takes for the bobblehead to reach the field from the top of the Green Monster?
