## Homework Statement

What work is done by the air on the spring?

k(The force constant)=640 N/m

x=2.0cm=0.020m

The air is coming out of the tire, into a pressure gauge pushing a spring 2.0cm.

## Homework Equations

Fx=x*k

W=F*D

## The Attempt at a Solution

First of all, I need to find the force in the equation of work.

Fx= (0.020m)(6.4x2N/m)

Force needs to be positive so I don't use the negative version of the equation since work done by the air needs to be positive thus needing a positive force.

Fx=12.8N

W=(12.8N)(0.020m)=0.26J

The work done by the air on the spring is approx 0.26J

Could someone verify my solution?
