A 2 kg mass has 40 J of potential energy with respect to the ground.Approximately how high is it above the ground?
A)1 m
B)2 m
C)3 m
D)4 m
E)none of these

Question

Quizplus · Accepted Answer

The potential energy (PE) is given by PE = mgh, where m is mass, g is the acceleration due to gravity (approximately 9.8 m/s²), and h is height. Solving for h: h = PE / (mg) = 40 J / (2 kg * 9.8 m/s²) ≈ 2 m.
