Momentum and Newton's Laws of Motion problem 2


Gases emitted by a jet engine at a mass flow rate of 4 and speed of 6 falls on a wall and bounces off it at the same speed. The angle of incidence and the angle of reflection are with respect to the vertical. How much force does the wall exert on the gases?
