Problem 18.18 The wheel has a mass of 100 kg and a radius of gyration of ko 0.2 m. A motor supplies a torque M (400+900) N m, where is in radians, about the drive shaft at O. Initially the car is at rest when s = 0 and 0°. Neglect the mass of the attached cable and the mass of the car's wheels. (Figure 1) Part A Determine the speed of the loading car, which has a mass of 330 kg, after it travels s = 4 m. Express your answer to three significant figures and include the appropriate units.
