1. Homework Statement
A moose is running away at 25m/s. You fire an arrow at 30 degrees when it's 120m away. What must the velocity of the arrow be in order to hit it?
Please see attached picture, I'd type it out but I'm unsure how some of you type it out in the box which allows for several different math notations etc and so forth.
I assume it's because the 120m in the quadratic equation should be a postive and not a negative? But the distance is increasing as the moose runs away
