Understanding Rotational Motion: Solving for Linear and Angular Acceleration

[jano.sl]

Homework Statement

Consider a sphere that is placed at a table. The coefficient of kinetic friction between the sphere and the table is μ. At time t = 0, the velocity of the center of mass of the sphere is Vo = 0, and the sphere is rotating with respect of the horizontal axis with angular velocity ωo.
Find the linear acceleration of the center of mass of the sphere and the angular acceleration of sphere. (picture attached)

What in particular are you having trouble understanding? The sphere is skidding on the surface if you're wondering how it can spin yet not move linearly.
