Find the gravitational potential energy on the first day

Reference no: EM1322209

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?
