1 A car with a tire radius of 0.26 m accelerates from 0 to 27 m/s in 9.5 seconds. What is the angular acceleration of the wheel?

2 A lead filled bicycle wheel of radius 0.47 m and mass 2.2 kg is rotating at a frequency of 1.9 revolutions per second. What is the moment of inertia?

4 The moment of inertia of a solid disk of mass, M, and radius, R, is ½ MR^{2}. Two identical disks, each with mass 2.7 kg are attached. The larger disk has a diameter of 0.87 m, and the smaller disk has a diameter of 0.45 m. If a force of 55 N is applied at the rim of the smaller disk, what is the angular acceleration?
