Answer:
ω= 2.095rad/sec
Explanation:
angular frequency(ω)=2πf
F is the frequency
Frequency of an oscillation is the number of cycles completed per second. One oscillation represents 1cycle. Thus for 13 oscillations, the glider completes 13 cycles.
F= 13/39 =[tex]\frac{1}{3}[/tex]Hz
angular frequency(ω)=2πf
angular frequency(ω)=2π * [tex]\frac{1}{3}[/tex]
= 2*[tex]\frac{22}{7}[/tex]*[tex]\frac{1}{3}[/tex]rad/sec
ω= 2.095rad/sec
