Calculate the kinetic energy of the airliner at takeoff and calculate the gravitational potential energy of the airliner when cruising .
( that's the rest of the question)
A Boeing 747 has a mass of 400,000kg and a takeoff speed of 100m/s . It cruises at a height of 10,000m at a speed of 255m/s

Use
KE=(1/2)mv^2
GPE=mgh
where
m=mass of plane
v=velocity
h=height of plane assuming reference plane is ground level.
g=9.81 m/s²
Use consistent units.
