Answer:
300 J
Explanation:
The gravitational potential energy of the performer is given by:
[tex]U=mgh[/tex]
where
(mg) is the weight of the performer, equal to the product between mass (m) and gravitational acceleration (g)
h is the height of the performer above the ground
In this problem, we have
(mg) = 60.0 N
h = 5.0 m
Substituting into the formula, we find
[tex]U=(60.0 N)(5.0 m)=300 J[/tex]
