Question

What is the gravitational potential energy of a 55-kg person that has climber a 4,000 meter tall mountain?

Bonus: if one snickers bar is 1,100,000 joules of energy, how many snickers bars would provide enough fuel to climb the mountain ?

Answer 1

the gravitational potential energy equation is Eg = mass x gravity x height, gravity is always 10 on Earth, so youre equation would be “Eg =55 x 10 x 4,000” so your answer should be “Eg = 2,200,000 J”. for the bonus question, they would need 2 snicker bars :)
