The angular velocity ω\omega is ω=VR=3.5m/s0.75m4.67rad/s.\omega = \dfrac{V}{R} = \dfrac{3.5\,\mathrm{m/s}}{0.75\,\mathrm{m}} \approx 4.67\,\mathrm{rad/s}.

Why is this formula correct? The angular velocity ω\omega is ω=2πT=2π2πR/V=VR.\omega = \dfrac{2\pi}{T} = \dfrac{2\pi}{2\pi R/V} = \dfrac{V}{R}.
