Answer:
A. [tex]\omega=11.1121\ rad.s^{-1}[/tex]
B. [tex]f=1.7685\ Hz[/tex]
C. [tex]T=0.5654\ s[/tex]
Explanation:
Given:
A)
for a spring-mass system the frequency is given as:
[tex]\omega=\sqrt{\frac{k}{m} }[/tex]
[tex]\omega=\sqrt{\frac{56.8}{0.46}}[/tex]
[tex]\omega=11.1121\ rad.s^{-1}[/tex]
B)
frequency is given as:
[tex]f=\frac{\omega}{2\pi}[/tex]
[tex]f=\frac{11.1121}{2\pi}[/tex]
[tex]f=1.7685\ Hz[/tex]
C)
Time period of a simple harmonic motion is given as:
[tex]T=\frac{1}{f}[/tex]
[tex]T=0.5654\ s[/tex]
