A green sedan weighing 25,000 Newtons is put on a lift supported by a piston with
a cross sectional area of 0.1 square meters.  What is the minimum force that must
be exerted by the air compressor that pushes down on the oil in the reservoir of the lift system in order to lift the sedan if the cross-sectional area of the reservoir
is 1.0 square meter? (Hint: use Pascal’s Law.)

pressure in the oil is the same on both sides
p *.1 = 25,000
p = 250,000N/m^2
F = p*A = 250,000 *1 = 250,000 N
