Problem

A pizza chef spins a circular piece of dough of radius

R = 25\;\text{cm}

and mass

m = 0.8\;\text{kg}

above his head. The dough rotates as a rigid disk about a vertical axis through its center. To prevent the dough from tearing, the tangential speed at the outer edge must not exceed

v_{\text{max}} = 4.0\;\text{m/s}

. If the chef spins the dough at exactly this maximum safe speed, what is the kinetic energy of the spinning dough?
