0.0 A 30-kg ball is sitting on top of a 50 m hill. The ball rolls down the hill. As the ball reaches the very bottom of the hill, what is its
velocity? (Assuming no energy is lost due to friction. This would mean that the PEtop = KEbottom)

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.
