In the process of changing a flat tire, a motorist uses a hydraulic jack. she begins by applying a force of 64 n to the input piston, which has a radius r1. as a result, the output plunger, which has a radius r2, applies a force to the car. the ratio r2/r1 has a value of 9.3. ignore the height difference between the input piston and output plunger and determine the force that the output plunger applies to the car.
