Asked by Saiba

One can work out by either lifting weights or using a tension band, which is like a big rubber band. If we model the rubber band as a big spring with spring constant 400 N/M how far in meters must I stretch the the band so it applies a force equivalent to the gravitational force on a 10kg weight?

Fg = m*g = 10kg * 9.8N/kg = 98 N.

d = (98/400) * 1m = 0.245 m.
