Solve the all parts of following question:
Question: A catapult launcher on an aircraft carrier accelerates a jet from rest to 67m/s. The work done by the catapult during the launch is 8.0×107J.
Part I: What is the mass of the jet?
Part II: If the jet is in contact with the catapult for 5.0s, what is the power output of the catapult?
I need help to find the power output of the catapult.
Through the compression stroke of a diesel engine, air is compressed from 1 atm and 27 degrees C to 1/25 of its initial volume. Suppose that Cv for air is 2R and that the compression is adiabatic. How much work is required per gram - mole?
