A student pushes a 12 kg block on a frictionless horizontal surface if the block is initially at rest what is the speed of the block after the student pushes the block for five seconds with an acceleration of 2 m/s squared

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.
