M=R1L-F%28L-x%29
M=R1L-FL%2BFx%29
M-Fx=R1L-FL%29
R1L-FL=M-Fx%29
L%28R1-F%29=M-Fx%29 divide by %28R1-F%29
L=%28M-Fx%29%2F%28R1-F%29%29

T%2Bmg=%28mv%5E2%29%2FR
T=%28mv%5E2%29%2FR-mg
%28mv%5E2%29%2FR-mg=T
m%28v%5E2%2FR-g%29=T
m%28%28v%5E2-gR%29%2FR%29=T multiply by R
m%28v%5E2-gR%29=TR divide by %28v%5E2-gR%29
m=%28TR%29%2F%28v%5E2-gR%29
