A Projectile Is Launched from Ground Level at an Angle

question 18

Multiple Choice

A projectile is launched from ground level at an angle of  with the horizontal. The initial velocity is feet per second and the path of the projectile is modeled by the parametric equations and .Use a graphing utility to graph the paths of a projectile launched from ground level with the values given for  and . Use the graph to approximate the maximum height and range of the projectile to the nearest foot. ,

• A)maximum height  100 feet range  9 feet
• B)maximum height  9 feet range  100 feet
• C)maximum height  67 feet range  188 feet
• D)maximum height  188 feet range  67 feet
• E)maximum height  43 feet range  8 feet
