In a car lift, compressed air exert a force of, F1 on a small piston having a radius of 5.0cm. This pressure is transmitted to a second piston of radius of 15cm. The mass of the car is 1350kg. Acceleration due to gravity g=10s-2 . How high will the car be lifted if 785N force is applied on the smaller piston?
