Recall that the flight of a projectile can be modeled with the parametric equations: ,
where t is in seconds, vo is the initial velocity, is the angle with the horizontal, and x and y are in feet.
A missile is fired from a ship at an angle of 31°, an initial height of 13 feet above the water's surface, and at a speed of 5500 feet per second. How long will it be before the missile hits the water? Round to one decimal place.
A) 177.0 seconds
B) 354.1 seconds
C) 88.5 seconds
