The cable cars in San Francisco are pulled along their tracks by anunderground steel cable that moves along at 9.5 mph. The cable isdriven by large motors at a central power station and extends, via anintricate pulley arrangement, for several miles beneath the city streets.The length of a cable stretches by up to 100 ft during its lifetime. Tokeep the tension constant, the cable passes around a 1.5-m-diameter"tensioning pulley" that rolls back and forth on rails, as shown in (Figure 1). A m = 2000 kg block is attached to the tensioning pulley'scart, via a rope and pulley, and is suspended in a deep hole.mT =1.5 mCableRailPart AWhat is the tension in the car's cable?Express your answer with the appropriate units.
