Question

If Total energy of an aircraft is found to be 1200 unit and kinetic energy is 1100 unit then, determine the potential energy.

(a) 100 unit

(b) 213 unit

(c) 456 unit

(d) 500 unit

The question was asked during an interview for a job.

My enquiry is from Flight Mechanics in section Performance and Flight Mechanics of Aircraft Design

Answer 1

Right choice is (a) 100 unit

Explanation: Potential energy = Total energy – kinetic energy = 1200 – 1100 = 100 unit.
