In one day, a 85 kg mountain climber ascends from the 1440 m level on a vertical cliff to the top at 2360 m . The next day, she descends from the top to the base of the cliff, which is at an elevation of 1310 m .

a) What is her gravitational potential energy on the first day? If you choose the reference level for zero potential energy at:

a. the top of the cliff.

b. 1440 m level.

c. 1310 m level.

b) What is her change in gravitational potential energy on the first day?

c) What is her change in gravitational potential energy on the second day?
