Free-Fall Motion As a promotion for the Houston Astros downtown ballpark, a competition is held to see who can throw a
baseball the highest from the front row of the upper deck of seats,
83 ft above field level. The winner throws the ball with an initial
vertical velocity of 92 ft/sec and it lands on the infield grass
(a) Find the maximum height of the base ball.
(b) How much time is the ball in the air?
(c) Determine its vertical velocity when it hits the ground.
Baseball Throwing Machine The Sandusky Little League
uses a baseball throwing machine to help train 10-year-old players
to catch high pop-ups. It throws the baseball straight up with an
initial velocity of 48 ft/sec from a height of 3.5 ft.
(a) Find an equation that models the height of the ball 1 seconds
after it is thrown.
(b) What is the maximum height the baseball will reach? How
many seconds will it take to reach that height?
