The security team on a college campus has a capacitor pack that can be used to start a car with abad battery. It takes about 5000 J to start a car.When the capacitor pack is fully charged, it has an initial voltage of 14.5 V. The capacitor pack can beused to start more than one car without recharging, but when the voltage of the pack has droppedto 12 V, the pack to be recharged.The net capacitance of the pack is 500 F.How many cars can be started with the capacitor pack without recharging the capacitor pack?
