Suppose you climb the stairs of an eight-story building, about 24 m high, and your mass is 70 kg. The gravitational potential energy you gain is about
A) 16,500 calories.
B) 40 calories.
C) 16,500 Joule.
D) 40 Joule.

Question

Quizplus · Accepted Answer

The gravitational potential energy gained by the person is given by the formula:
GPE = mgh
where m is the mass of the person (70 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height climbed (24 m).
GPE = 70 x 9.8 x 24
GPE = 16,464 Joule (approx.)
Therefore, the correct answer is C) 16,500 Joule.
