Question #5154

A pupil attached a rubber band to a door handle and pulled it until it opened. She measured the distance the band stretched and found this to be 2.5 cm. What was the size of the force she applied to open the door?

Expert's answer

To find the force applied to the door we need to know the coefficient of elasticity of a rubber band. Let c be this coefficient, then the force is

F = c*ΔL = c*2.5.

F = c*ΔL = c*2.5.
