Suppose a yo-yo has a center shaft that has a $0.220\mathrm{cm}$ radius and that its string is being pulled. (a) If the string is stationary and the yo-yo accelerates away from it at a rate of $2.00\mathrm{m}/{\mathrm{s}}^2$, what is the angular acceleration of the yo-yo in rad/s? $\mathrm{rad}/{\mathrm{s}}^2$ (b) What is the angular velocity in rad/s after 0.750 s if it starts from rest? $\mathrm{rad}/\mathrm{s}$ (c) The outside radius of the yo-yo is $3.30\mathrm{cm}$. What is the tangential acceleration in $\mathrm{m}/{\mathrm{s}}^2$ of a point on its edge? $m/s^2$
