Answer:
Potential energy is 
Explanation:
The potential energy depends on the mass, the acceleration of gravity g and the height at which the object or person is.
Potential energy 
In this case we would need to know the exact mass of the hiker in order to calculate the potential energy.
But we know the values of g and h


So, the potential energy

m is the mass of the hiker, wich is not in the description of the problem.

P=W/t
P=Power
W=Work
t=Time
Convert 16 minutes in seconds:
16 mins = 960 secs
P=6720/960=7.23 W [Watt]
Average acceleration is difference in velocity divided by time.
(35 - 15)/2 = 10 m/s² downward
The shortest wavelengths that you can see are experienced
as violet light, or whatever is the last color you can see on the
"blue end" of the spectrum. It's not exactly the same for all eyes.
