A hydrulic jack in a mechanic's shop supports a car of mass M= 2.1 x 10^3 kg. The diameter of the piston in contact with the car is 22cm. A pump forces fluid into the cylinder below the piston through an input line that has an inside diameter of 1.0cm.
A) What pressure is required in the hydraulic jack to support the weight of the car?
B) What force must the pump exert on the fluid at the input to support the weight of the car?
