thanks

so, can angle in certain condition, here slope =1, be expressed by opposite/adjacent in right angle triangle? It mean angle = tangent??

It is working. Thanks, guys from yahoo and overflow struggle to answer. I did not overlook vectors, but was to obsessed with trigs. 1 smart mathematician got similar result, using trigs: tangent, arcus tangent and got assumption pi/4=r_y/r_x...ry=(pi_*r_x)/4...is it right? I do not know what is...

is it vy sin 45=uy+ayt?, it does not work. What plot?

I am not sure how to use trig for the NE direction. It is 45 degree or pi/4, slope= 1

u/initial velocity =v0, u is popular and very common in UK SUVAT: v=u+at, r= r0+u0t+1/2 a t^2

Help please
