Type the correct answer in the box. round your answer to the nearest whole number. calculate the man’s mass. (use pe = m × g × h, where g = 9.8 n/kg.) a man climbs a wall that has a height of 8.4 meters and gains a potential energy of 4,620 joules. his mass is about kilograms.

56 kg

Explanation:

The change in potential energy of the man is given by:

where

m is the man's mass

g is the gravitational acceleration

is the change in height of the man

In this problem, we have:

is the gain in potential energy

g = 9.8 m/s^2 is the gravitational acceleration

is the change in height

Re-arranging the equation and substituting the numbers, we find the mass:
