In a baseball game, Alex hits a ball with an initial velocity of at an angle of with the horizontal. The ball was struck at an initial height of feet. Alex will hit a homerun if the ball travels feet and has a height of at least feet. Does Alex hit a homerun? How far will the ball have traveled horizontally when it hits the ground?

Use parametric equations to solve this problem.
To determine when the ball will hit the ground, solve .
Since the velocity is given in ft/s, use for acceleration due to gravity.
