A 2-kg mass is held 4 m above the ground. What is the approximate potential energy of the mass with respect to the ground?

Question

Quizplus · Accepted Answer

The potential energy (PE) can be calculated using the formula PE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the height in meters. Substituting the given values, PE = 2 kg * 9.8 m/s^2 * 4 m = 78.4 J, which is approximately 80 J.
