What is the difference in KE between a 52.5 kg person running 3.50 m/s and a 0.0200 kg bullet flying 450 m/s? (Unit = J)
Answers: 3
![E_{k} =\frac{1}{2}*52.2*(3.5)^{2} \\ E_{k} =319.72[J]](/tpl/images/0920/6293/8c0ef.png)
![E_{k} =\frac{1}{2} *0.02*(450)^{2} \\E_{k}=2025 [J]](/tpl/images/0920/6293/03e5e.png)
