A 2-kg mass has 40 J of potential energy with respect to the ground. Approximately how far is it located above the ground?

Question

Quizplus · Accepted Answer

The potential energy (PE) of an object is given by the formula PE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (approximately 9.8 m/s^2 on the surface of the Earth), and h is the height in meters. Rearranging the formula to solve for h gives h = PE / (mg). Substituting the given values, h = 40 J / (2 kg * 9.8 m/s^2) = 2.04 m, which is approximately 2 m.
