As part of our data analysis, we need to find 'g' through a calculation and then back it up with graphical representation. Since I have 'u', 's' and 't', the choice of equation is rather simple: s=ut+1/2at^2. Then this needs to be converted so y=mx, it's by no means necessary, but I want to do it. I got told that t^2= (2sy)/(ay)=(2/ay) x (sy) is the conversion for y=mx, yet I it doesn't seem right to me. I'm also not sure whether that value of 'y' is that graphical value of 'y', but it doesn't look like it to me.
