    Is the Net Work Done Positive and Does It Function as a Heat Engine?

    Homework Statement A cylinder contains 2 moles of gas initially at state A it has a volume of 1*10^-2m^3 and a pressure of 4*10^5. It the is brought isobarically to state B where the new volume is 2*10^-2. It is then brought at a constant volume to state C where the temperature is the same as...

    Need help going over a momentum/spring problem

    1.Homework Statement A pellet gun is fired into a block of wood that is attached to a spring on a frictionless surface. The bullet remains in the wood and the block of wood and the bullet enter into a simple harmonic motion with Amplitude=11cm. The 5g bullet was traveling at 650m/s before...
