Recall That the Flight of a Projectile Can Be Modeled

Short Answer

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 gun is fired at an angle of 21°, and the bullet has an initial speed of 875 feet per second. How high does the bullet go, and when does it hit the ground? Round the altitude to the nearest foot and time to the nearest tenth of a second.
