ok so what i have so far is, for y: y= (1/2 a t^2) + (Vo cosθ t) (Vcosθ)^2 = (Vocosθ)^2 + 2ay for x: x= (1/2 a t^2) + (Vo sinθ t) (Vsinθ)^2 = (Vosinθ)^2 + 2ax so far how i see it is im going to substitute my 2 x equations and my 2 y equations, then ill have 2 equations left to subtitute which are θ and time.
