Thank you for any help
Are those kinematic equations for components of vectors, or for vectors themselves?Homework Statement

Sorry for the slow response.If you click the first picture, you will have an understanding equal to mine. I'm sorry.
Sorry for the slow response.
I should have been more direct with my earlier response.
The set of kinematic equations you have(v2)2=(v1)2+2axare valid for each component of displacement, velocity, and acceleration.
(v2)=(v1)+at
x2=x1+(v1)t+1/2at2
So you have two such sets of kinematic equations:(v2)x2 = (v1)x2 + 2axx
(v2)x = (v1)x + axt
x2 = x1 + (v1)xt + 1/2axt2
(v2)y2 = (v1)y2 + 2ayy
(v2)y = (v1)y + ayt
y2 = y1 + (v1)yt + 1/2ayt2
What did you get for answers?It makes sense now. thank you.
