Hi guys, on the topic of the position of a projectile, Physics In Focus says: Sx = x0 + uxt and Sy = y = uyt +1/2ayt2.
What do the x0 and y 0 mean? I am struggling to understand this.
Thank you so much for your time guys!!

Well firstly I don't see any y0, and the x0 is what horizontal distance the projectile starts from with reference to your origin. For example in the x-y plane if you take (0,0) as the place of where displacement is measured and your projectile is launched from (1,0). Then it's total displacement from the reference point is 1 + uxt where '1' is x0. Of course this would be different if say you were measuring from (2,0), then it would be (2)+uxt where (2) is x0.
