When a 15 newton force is applied to on end of a lever 100 cm long, a 60 newton weight is attached to the opposit end is lifted. What is the length of the input arm?

Please show all the steps.

\(15N\times x=60N\times(100cm-x)\)

 

\(15N\times x = 6000Ncm - 60N\times x\)

 

\(x=\frac{6000Ncm}{75N}\)

 

\(x=80cm\)

 

\( The\ length \ of \ the\ input\ arm \ is \ 80cm.\)
