Shortly after takeoff, an airplane ($m = 1900\:kg$) is flying at an altitude of $510\:m$ above the ground.
What is the gravitational potential energy (in Joules) of the airplane? Define the potential energy to be zero on the ground.
State the numerical value of the potential energy (in Joules) only, without units or commas. Do not use scientific notation.
