Answer:
[tex]T = 1.108\,s[/tex]
Explanation:
The period of a physical pendulum is:
[tex]T = \sqrt{\frac{I_{O}}{m\cdot g \cdot L} }[/tex]
[tex]T=2\cdot \pi \sqrt{\frac{\frac{1}{3}\cdot m \cdot L^{2} }{m\cdot g\cdot L} }[/tex]
[tex]T=2\cdot \pi \sqrt{\frac{L }{3\cdot g} }[/tex]
The length of the leg is approximately the height of the person:
[tex]L = 0.915\,m[/tex]
The period is:
[tex]T = 2\cdot \pi \sqrt{\frac{0.915\,m}{3\cdot (9.807\,\frac{m}{s^{2}} )} }[/tex]
[tex]T = 1.108\,s[/tex]
