A Navy jet (see the figure) with a weight of 202 kN requires an airspeed of 88.0 m/s for liftoff. The engine develops a maximum force of 100 kN, but that is insufficient for reaching takeoff speed in the 94.0 m runway available on an aircraft carrier. What minimum force (assumed constant) is needed from the catapult that is used to help launch the jet? Assume that the catapult and the jet's engine each exert a constant force over the 94.0 m distance used for takeoff.

Question
Transcribed Image Text:A Navy jet (see the figure) with a weight of 202 kN requires an airspeed of 88.0 m/s for liftoff. The
engine develops a maximum force of 100 kN, but that is insufficient for reaching takeoff speed in
the 94.0 m runway available on an aircraft carrier. What minimum force (assumed constant) is
needed from the catapult that is used to help launch the jet? Assume that the catapult and the jet's
engine each exert a constant force over the 94.0 m distance used for takeoff.
Expert Solution
Step 1
Given that,
weight of Navy jet 202 kN = 202000 N
Minimum speed required for liftoff is 88.0 m/s
Engine can generate a maximum force of 100 kN = 100000 N
Initial speed is 0 m/s
Distance of 94 m.
