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?
