Given data:
The given time is t=1 s.
From the graph following observation can be made,
The amplitude of the graph is A=10 cm=0.1 m.
The time period is t=1 s.
The angular velocity can be calculated as,
[tex]\begin{gathered} \omega=\frac{2\pi}{t} \\ \omega=\frac{2\pi}{1} \\ \omega=6.3\text{ rad/s} \end{gathered}[/tex]
The speed can be at t=1 s will be,
[tex]\begin{gathered} v=A\omega \\ v=(0.1)(6.3) \\ v=0.63\text{ m/s} \end{gathered}[/tex]
Thus, the spee
