Larry's gravitational potential energy is 1870 J as he sits 2.20 m above the ground in a sky diving airplane before it takes off. What is Larry's gravitational potential energy when be begins to jump from the airplane at an altitude of 923 m?

Sagot :

Potential Energy = Mass x Gravity x Height
PE = 1870 kg (9.8m/s²) (2.20m)
= 40317.2 Joules
