Swing

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

Correct result:

x =  27.3684 cm

Solution:


12•130 = 57 x

12•130 = 57•x

57x = 1560

x = 52019 ≈ 27.368421

Our simple equation calculator calculates it.
