Can you site where you gathered this information?

I was interested in how the equation simplified down to what is shown, thought I might share the results.

E_acc = P ( t2 + (t3P/P’))
P’=PT/(t1+t3)

E_acc = P ( t2 + (t3P/(PT/(t1+t3))))
= P ( t2 + (t3P/1) ((t1+t3)/PT))
= P ( t2 + (t3/1)((t1+t3)/T))

n / m = E_acc / p’ * o / c

= [P ( t2 + (t3/1 ...
