Swing

A child weighing 12 kg is sitting on a swing at a distance of 130 cm from the rotation axis. How far away from the rotation (center) axis must sit down his mother weighs 57 kg if she wants to be a swing in balance?

Correct answer:

x =  27.37 cm

Step-by-step explanation:

m1=12 kg m2=57 kg l1=130 cm  M1=M2  m1 l1=m2 x 12 130=57 x  57x=1560  x=5201927.368421=27.37 cm
