Energy problem 47


A 600 kg aircraft accelerates in a horizontal direction from a speed of 180 km/h to 216 km/h against air resistance of magnitude 1200 N and covers a distance of 500 m.

  • Calculate the kinetic energy of the aircraft at the speed of 180 km/h.

  • What is the change in the kinetic energy of the aircraft during acceleration?

  • Calculate the average thrust with which the engine acts on the airplane during acceleration.
