A piston motion moves a 25-kg hammerhead ver tically down 1 m from rest to a velocity of 50 m/s in a stamping machine. What is the change in total energy of the hammerhead?
Answers: 1
![\Delta E_{ham} = (25\,kg)\cdot [\frac{1}{2}\cdot (50\,\frac{m}{s} )^{2} - (9.807\,\frac{m}{s^{2}} )\cdot (1\,m)]](/tpl/images/0539/2343/0b4ce.png)
