Question 798565: Have you been to a baseball game lately? Did anybody hit a home run? The trajectory of a baseball is usually very complicated, but we can get help from The Physics of Baseball, by Robert Adair. According to Mr. Adair, after t seconds, starting 1 sec after 35o angle, rotating with an initial backspin of 2000 revolutions per minute (rpm), and hit about 110 mph is given by
H(t) = -80t2 +340t - 260 (in feet)
1. How many seconds will pass before the ball hits the ground?
The distance traveled by the ball is given by
D(t) = -5t2 + 115t � 110 (in feet)
2. How far will the ball travel before it hits the ground?
3. Using D(t), how far will a ball travel in 6 seconds, the time it takes it takes a high fly ball to hit the ground?
