How to calculate the energy of a swinging hammer?
John Henry aided in building the railways by swinging his 7 Kg (16 lb) hammer. Suppose he exerts a force of 500 N (a bit more than 100 lb) on the hammer handle while it moves a distance of 0.4 m. At the same time, the hammer head descends a distance of 2 m.
How much energy does the hammer have (assuming it is all in the form of the kinetic energy of the hammer head)?
There are two froms of energy imparted to the hammer:
1) The force of John Henry - E(JH) = 500N*0.4m = 200J
2) The potential energy of descending - E(P) = 7kg * 9.8m/s^2 * 2m = 137J
Adding the two E(JH) + E(P) = 200J + 137J = 337J
