The path of a projectile is modeled by the parametric equations

where x and y are measured in feet.

(a) Use a graphing utility to graph the path of the projectile.
(b) Use a graphing utility to approximate the range of the projectile.
(c) Use the integration capabilities of a graphing utility to approximate the arc length of the path. Compare this result with the range of the projectile.
