The small car shown in Figure 8, which has a mass of 20 kg

The small car shown in Figure 8, which has a mass of 20 kg, rolls freely on the horizontal track and carries the 5 kg sphere mounted on the light rotating rod with r = 0.4 m. A geared motor drive maintains a constant angular speed ? ? = 4 rad/s of the rod. If the car has a velocity of v = 0.5 m/s when ? = 0, calculate v when ? = 270° using linear momentum. Neglect the mass of the wheels and any friction.
