A 2-kg mass that weighs 20 N has 40 J of potential energy relative to the ground.What is its height?

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. Given that the potential energy is 40 J, we can solve for h: 40 = 2 * 9.8 * h, which simplifies to h = 40 / (2 * 9.8) = 2 m.
