A 0.145 kg baseball pitched at 39.0 m/s is hit on a horizontal line drive straight back towards the pitcher at 59.0 m/s. If the contact time between
bat and ball is 0.001 s, calculate the average force between the ball and
bat contact. (NO Scientific Notation!)

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.
