Suppose a soccer player kicks a ball that is a horizontal distance of 39.3 m from the goal. Find the initial
speed of the ball, in units of m/s, if it just barely passes over the goal, 3.05 m above the ground. The
initial angle of the kick is 33.1° above the horizontal.

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.
