Question

You are avoiding your physics homework by doing a little physics experiment on the swing set near your home. You make sure you pick a swing that has recently been greased so that friction will be minimal. By pumping your legs back and forth, you manage to get swinging from an initial height of about 3 feet above the ground (when the swing is at rest) to a maximum height of 6 feet above the ground. You estimate that the swing seat has a mass of about 1 kg. How much energy have you transferred into the swing seat?

Explanation / Answer

energy= Mg(h2-h1)=1*9.81*(6-3)*0.3048=8.97 J
