If the man has a mass of 95kg and is running towards the girl at a velocity of 3m/s and the woman has a mass of 65kg is running 2m/s, what is their velocity after the collision ?

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
