Astudent driving nails into a piece of wood lifts a 2.25 kg hammer it on the nail. if the nail is driven 0.0100 m into the wood, calculate the average force on the hammer 0.300 m above the top of a nail and then simply drops

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 50 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/k.
