Asked by zianna
In one day, a 75-kg mountain climber ascends from the 1500-m level
on a vertical cli to the top at 2400 m. The next day, she descends
from the top to the base of the cli , which is at an elevation of 1350 m.
What is her change in gravitational potential energy (a) on the first
day and (b) on the second day.
