When a 5.0kg cart undergoes a 2.2m/s increase in speed, what is the impulse of the cart

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.

Why does gravity have a lesser than grater effect on higher altitudes?
