I'm currently studying Kinematics but I've been out of H.S. for nine yrs. now. I know this is more of a math problem but could someone pls. show me how ;


a=(vf-vi) / t can be manipulated to find vf, as vf = vi + at

Much appreciated!

Welcome to the forums.

I think your equations aren't quiet correct. Shouldn't they really be the following?

a = (vf - vi) / t

vf = vi + at

I think that's what he's got.

Like this:

a = \frac{(v_f - v_{i})}{t}

at = v_f - v_i

v_f = v_i + at
 
Thanks a lot..simple I know but you forget these things if you don't keep using them...Thanks again
