For physics show-and-tell, you want to impress the class by sipping water through a long straw. If you hold the straw vertically, determine the length of the longest straw that you could, in principle, drink from in this manner.

Suppose a soccer ball is kicked from the ground at an angle 20.0º above the horizontal at 8.00 m/s. the y-velocity is determined to be 2.74 m/s. how long will the ball be in the air? assume the ball lands at the same height at which it was kicked.
