Question
A student in Denver (altitude=1 mile=1609 m above sea level) brings a physics book of mass 1 . 2 kg to the top of a ten story building of height 33 m and holds the book over her head 149 cm above the roof. What is the gravitational potential energy, Ug, of the book?1. Ug = 406.016 J. 2.Ug = 0 J. 3.Ug = 17.5403 J. 4.Ug = 19347.2 J. 5.Cannot be determined
I entered number 4 at it was wrong. I did m*g*h.

Explanation / Answer
h = 33 + 1.49 = 34.49 m
U = m*g*h = 1.2*9.8*34.49 = 406 J
option a is the correct answer............
