A bicycle wheel is descending an icy hill by sliding against the hill surface. The wheel cannot roll since the wheel's axle has rusted solid. If the velocity of the wheel's center of mass is 2 m/s and the wheel mass is 1 kg, what is the wheel's kinetic energy? can't tell, need to know the wheel's polar moment of inertia (Iz) 2 Nm can't tell, need to know the wheel's angular
