Multiple Choice

A projectile is fired from a cannon at ground level at an angle of 2424 ^ { \circ } with an initial velocity of 54 ft/sec.How far from the cannon does the projectile land? Round your answer to the nearest tenth of a foot.
Use the following formulas
x=(v0cosθ) ty=16t2+(v0sinθ) t+s0\begin{array} { l } x = \left( v _ { 0 } \cos \theta \right) t \\y = - 16 t ^ { 2 } + \left( v _ { 0 } \sin \theta \right) t + s _ { 0 }\end{array}
