A soccer ball is kicked from the ground at an angle of θ = 54 degrees with respect to the horizontal. The ball is in the air for a time tm = 2.4 s before it lands back on the ground.

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.
