SUVAT Equations?

Question

I'm a latecomer to physics and I'm working through problems from text books. I understand the SUVAT equations as they are presented but some problems require me to turn the equation round (eg if v^2 = u^2 + 2at then t = ?)- I don't know how to do this and the worked examples just quickly show the altered equation - can someone help me? PLEASE

Answer 1

If v^2 = u^2 + 2at

then fir you need to subtract u^2 from each side-:

v^2 - u^2 = 2 a t

not if you want to work out t, you must divide each side by 2a-:

(v^2 - u^2) / 2 a = t

easy eh??
