Homework Equations
Below.
The Attempt at a Solution
A.
[itex]W=Fd[/itex] 2000N x 0.001m = 2J
B.
This is where I am stuck. Can I assume that the pressure doesn't change when it is pushed in because it says that it is pushed in "suddenly"?
If so then I get: [itex]W = \int p \cdot dV = p(V_f - V_i)[/itex] 105Pa x (0.01m^2 x 0.001m) = 1.05E-3 J
C
Is this just the difference between the two above i.e. 2 - 1.05E-3 = 1.99895J?
I get the feeling this is wrong since I didn't use the information that its 1 litre and 300K anywhere here...
