Answer to relevant QuestionsLocate the center of mass of the system shown in Fig. 6.39 (a) If all of the masses are equal; (b) If m2 = m4 = 2m1 = 2m3; (c) If m1 = 1.0 kg, m2 = 2.0 kg. m3 = 3.0 kg and m4 = 4.0 kg. You are traveling north and make a right-hand turn east on a flat road while driving a car that has a total weight of 3600 lb. Before the turn, the car was traveling at 40 mi/h, and after the turn is completed you have ...Many curves have banked turns, which allow the cars to travel faster around the curves than if the road were flat. Actually, cars could also make turns on these banked curves if there were no friction at all. Explain this ...Two gear wheels with radii of 25 cm and 60 cm have interlocking teeth. How many radians does the smaller wheel turn when the larger wheel turns 4.0 rev? A race car makes two and a half laps around a circular track in 3.0 min. What is the car’s average angular speed?
