I just put it infront of sin, since v0 is the starting velocity. I think 1.7m make more sense now. Thank you

Now that I notice.. . Do i put it infront of sin?

I was stuned about that either but I dont think thats important here. I think it is more so about calculating with vectors

So the equation is the problem. But I don't know where the mistake is or is the approach wrong. I'm sure I solved it properly. It was t=...

I created a Vector which describes the direction of the medium. with r=(x(t),y(t))=((x0+cos(b)*t+0*t^2/2),(y0+sin(b)*t-9.81*t^2/2)) I...
