**Damon**, Friday, February 8, 2013 at 8:01amFx = F1 + F2 cos T

Fy = F2 sin T

F = sqrt (Fx^2+Fy^2)

Fx^2 = F1^2 + 2 F1F2 cos T + F2^2 cos^2 T

Fy^2 = F2^2 sin^2 T

sum = F1^2 + 2 F1F2 cos T + F2^2(sin^2T+cos^2T)

sum = F1^2 + 2 F1 F2 cos T + F2^2

so

F = sqrt (F1^2 + 2 F1 F2 cos T + F2^2)

and

m = F/a

=(1/a)sqrt(F1^2 + 2 F1 F2 cos T + F2^2)
