Question

(b) Find the increase in the car's gravitational potential energy when it is raised 1.00 m.

(d) Calculate the work done by P in moving the smaller piston.

 

(a) Find the force P that must be applied to a piston of area 10.10 cm2 to produce sufficient fluid pressure to support a car weighing 10,151 N by means of a
column of fluid of cross sectional area 315 cm² as seen in the figure below.
325.47 N
(b) Find the increase in the car's gravitational potential energy when it is raised 1.00 m.
1051 J
(c) How far must the smaller piston move in order for the larger one to move 1.00 m?
31.19 m
(d) Calculate the work done by P in moving the smaller piston.
325.48 N
Compare your answer with the answer to part b.
