Use the following information to answer questions 1 and 2. George is standing on the top of a 275 foot building. He throws a ball straight up into the air. The ball's initial velocity is given as 48 ft./sec. The height, in feet, of the ball after t seconds is given by h=-16t2 + 48t + 275. 1) How long will it take for the ball to reach its maximum height above the ground? 2) What is the maximum height that the ball reaches? Use the following information to answer questions 3- 5. Shelly is standing on a platform 100 feet above the ground. She tosses a baseball straight up into the air. The formula h =-16t2 + 64t+100 models the ball's height h above the ground t seconds after it was thrown. 3) How long will it take for the ball to reach its maximum height above the ground? 4) What is the maximum height that the ball reaches? 5) How many seconds does it take for the ball to finally hit the ground (rounded to the nearest tenth of a second)? Use the following information to answer questions 6-8. Les is standing on the ground. He launches a model rocket straight up into the air. The formula s=-16t2 + 641 models the rocket's height s above the ground t seconds after it was launched. 6) How long will it take for the rocket to reach its maximum height above the ground? 7) What is the maximum height that the rocket reaches? 8) How many seconds does it take for the ball to finally hit the ground (rounded to the nearest tenth of a second)?
