A Projectile Is Launched from Ground Level at an Angle $\theta$

question 18

Multiple Choice

A projectile is launched from ground level at an angle of $\theta$ with the horizontal. The initial velocity is $v _ { 0 }$ feet per second and the path of the projectile is modeled by the parametric equations $x = \left( v _ { 0 } \cos \theta \right) t$ and $y = \left( v _ { 0 } \sin \theta \right) t - 16 t ^ { 2 } .$
Use a graphing utility to graph the paths of a projectile launched from ground level with the values given for $\theta$ and $v _ { 0 }$ . Use the graph to approximate the maximum height and range of the projectile to the nearest foot.
$$\theta = 50 ^ { \circ } , \quad v _ { 0 } = 104 \text { feet per second }$$

• A) maximum height \(\approx 12\) feet range \(\approx 171\) feet
• B) maximum height \(\approx 171\) feet range \(\approx 12\) feet
• C) maximum height \(\approx 99\) feet range \(\approx 333\) feet
• D) maximum height \(\approx 333\) feet \(\quad\) range \(\approx 99\) feet
• E) maximum height \(\approx 38\) feet range \(\approx 8\) feet
