Question

1) speed of bob?2)Show calculation for the speed of the bob:(write formula first, then insert value with unit, then find the result with unit)

Answer 1

Speed of bob:

`\begin{gathered} \omega=2\pi f \\ _{\text{ }}where\colon \\ f=(1)/(T) \\ \omega=(2\pi)/(T) \end{gathered}`

so:

`\begin{gathered} \omega=(2\pi)/(1.293) \\ \omega=4.83(rad)/(s) \end{gathered}`

`\begin{gathered} v=\omega\cdot r \\ so\colon \\ v=4.83\cdot0.22 \\ v=1.06(m)/(s) \end{gathered}`
