As stated in the strategy, choose a coordinate system where the x axis is horizontal and the y axis is vertical. note that in the strategy, the y component of the projectile's acceleration, ay, is taken to be negative. this implies that the positive y axis is upward. use the same convention for your y axis, and take the positive x axis to be to the right. where you choose your origin doesn't change the answer to the question, but choosing an origin can make a problem easier to solve (even if only a bit). usually it is nice if the majority of the quantities you are given and the quantity you are trying to solve for take positive values relative to your chosen origin. given this goal, what location for the origin of the coordinate system would make this problem easiest?
