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

If you click the first picture, you will have an understanding equal to mine. I'm sorry.Are those kinematic equations for components of vectors, or for vectors themselves?
Sorry for the slow response.If you click the first picture, you will have an understanding equal to mine. I'm sorry.
It makes sense now. thank you.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+1/2at^{2}
So you have two such sets of kinematic equations:(v2)_{x}^{2} = (v1)_{x}^{2} + 2a_{x}x
(v2)_{x} = (v1)_{x} + a_{x}t
x2 = x1 + (v1)_{x}t + 1/2a_{x}t^{2}
(v2)_{y}^{2} = (v1)_{y}^{2} + 2a_{y}y
(v2)_{y} = (v1)_{y} + a_{y}t
y2 = y1 + (v1)_{y}t + 1/2a_{y}t^{2}
What did you get for answers?It makes sense now. thank you.
