Recall that the flight of a projectile can be modeled with the parametric equations:
, where t is in seconds, ν_o is the initial velocity, θ is the angle with the horizontal, and x and y are in feet.
A missile is fired from a ship at an angle of 32°, an initial height of 20 feet above the water's surface, and at a speed of 4450 feet per second. How long will it be before the missile hits the water? Round to the nearest tenth of a second.
