Question

A hydraulic lift is used to jack a 940-kg car 42 cm off the floor. The diameter of the output piston is 19 cm , and the input force is 360 N .

A) What is the area of the input piston? Express your answer using two significant figures.

B)What is the work done in lifting the car 42 cm ? Express your answer using two significant figures.

C)If the input piston moves 14 cm in each stroke, how high does the car move up for each stroke? Express your answer using two significant figures.

D)How many strokes are required to jack the car up 42 cm ? Express your answer using two significant figures.

Double check answers as I have gotten them wrong a couple times :/
