Answer:
The angular speed of the pendulum is 3.138 rad/s.
Step-by-step explanation:
Given that,
Length = 99.5 cm
Mass = 185 g
We need to calculate the angular speed
Using formula of angular speed
![\omega=\sqrt{(g)/(l)}](https://img.qammunity.org/2020/formulas/physics/college/3822jcjvqcf9gb8duxkadf6frc3e90x8xs.png)
Where, l = length
g = acceleration due to gravity
Put the value into the formula
![\omega=\sqrt{(9.80)/(99.5*10^(-2))}](https://img.qammunity.org/2020/formulas/physics/college/tqgn5gmmxudjb4h3285f77c9k26wgbtf6j.png)
![\omega=3.138\ rad/s](https://img.qammunity.org/2020/formulas/physics/college/8t38aotj6dciozt6qx0ah5pzpoqaqoenx2.png)
Hence, The angular speed of the pendulum is 3.138 rad/s.
