Consider a situation where you carry a 20-N box up a flight of stairs, raising its elevation by 5 m. The increase of potential energy of the box is

Question

Quizplus · Accepted Answer

The potential energy gained by the box is given by the equation PE = mgh, where m is the mass of the box, g is the acceleration due to gravity (approximately 9.8 m/s^2), and h is the vertical height gained by the box. Therefore, PE = (20 N)/(9.8 m/s^2) x 5 m = 102 J (rounded to the nearest whole number). Thus, the increase in potential energy of the box is approximately 100 J, so the correct answer is choice C.
