Big guns on naval ships must fire projectiles many kilometers. To do this, the
projectile must also go high into the air. Suppose that the initial upward velocity
of a projectile is 300 m/sec.
a. How high will the projectile be 20 seconds after it is fired?
b. When will it reach two kilometers above where it was fired?
c. Will it ever be 5000 meters above where it was fired? Explain.
d. How long does it take to reach the target, which is at the same level as the
