The frame of the roller has a mass of 5.5 Mg and a center of mass at G. The roller has a mass of 2 Mg and a radius of gyration about its mass center of k_A = 0.45 m. If a torque of M = 600 N · m is applied to the rear wheels, determine the speed of the compactor in t = 4 s, starting from rest. No slipping occurs. Neglect the mass of the driving wheels.
