Answer:

599.5 m

Explanation:

The gain in gravitational potential energy of the man is given by:

$\Delta U=mg\Delta h$

where

m is the man's mass

g is the gravitational acceleration

$\Delta h$ is the change in height of the hiket

In this problem, we have the following data:

U = 470,000 J

g = 9.8 m/s^2

m = 80 kg

Solving the formula for $\Delta h$ , we find:

$\Delta h = \frac{U}{mg}=\frac{470,000}{(80)(9.8)}=599.5 m$
