Question

The aircraft lands with a velocity of 71 m/s.

The mass of the aircraft is 3.6 × 105 kg.
Calculate the kinetic energy of the aircraft as it lands.

Answer 1

Step-by-step explanation:

Given:

V = 71 m/s

m = 3.6·10⁵ kg

___________

Ek - ?

Kinetic energy

Ek =m·V²/2

Eki = 3.6·10⁵·71² / 2 ≈ 907·10⁶ J = 907 MJ
