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 projectile is launched at a speed of 520 ft/sec at an angle of 31° with the horizontal. How far does the projectile travel (what is the horizontal distance) , and what is the maximum altitude? Round to the nearest integer.
A) 7,461 feet; 1,121 feet
B) 14,922 feet; 1,121 feet
C) 7,461 feet; 2,241 feet
D) 14,922 feet; 2,241 feet
