If a projectile is fired with an initial speed of
ft/s at an angle ? above the horizontal, then its position after t seconds is given by the parametric equations x = (
cos?)t y = (
sin?)t - 16t² where x and y are measured in feet.
Suppose a gun fires a bullet into the air with an initial speed of 1024 ft/s at an angle of 30° to the horizontal. What is the maximum height attained by the bullet?
