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? A)7.85 × 10⁵ J B)1.87 × 10³ J C)3.29 × 10⁴ J D)9.36 × 10² J E)4.22 × 10⁶ J

Question

Quizplus · Accepted Answer

Larry's gravitational potential energy is proportional to his height above the ground. At 923 m, his potential energy is much greater than at 2.20 m. Calculating using the ratio of heights, the potential energy at 923 m is approximately 7.85 × 10^5 J.
