The optimal amount of controversy is the midpoint of the two points where y=0, and the desired voter turnout is 100%. The two points where citizens of the country are not likely to turnout are at 49% and 69%.

The Earth Space Defense unit on Jupiter needs rockets that can be fired at full power to a height of over 62,500 miles (for some reason) in order to hit the alien ships from a safe distance. For some reason, they wish to ensure that they are not within the fallout zone of the nuclear rockets. The danger zone of the rocket is 50 miles.

You have to use the velocity formula. So you begin with how high the ball is thrown from, 6 feet high. The ball will travel at a speed of 12 feet per second. Gravity also has to be factored in, reducing the ball's speed by 5 feet per second.

He wanted to take the shot so that  the ball went into the basket as its height started to decrease.  The ball moved at 15 feet per second, but the gravitational pull was at 5.5 feet per second. At what point would the ball go into the basket? In other words, what is the vertex of this parabola?

Now like any normal teenager in the 21st century you take out your bow and arrow and do just that. 
When will the arrow land back on the ground with the following calculations?
