Question

Consider an airplane with a jet engine attached to the tail section that expels combustion
gases at a rate of 18 kg/s with a velocity of V = 300 m/s relative to the plane (Fig. 2). During
landing, a thrust reverser (which serves as a brake for the aircraft and facilitates landing on
a short runway) is lowered in the path of the exhaust jet, which deflects the exhaust from
rearward to 1500
. Determine
(a) The thrust (forward force) that the engine produces prior to the insertion of the thrust
reverser.
(b) The braking force produced after the thrust reverser is deployed.
