The gravitational potential energy of the circus performer walking on the tightrope above the ground is 4900J.
Given the data in the question;
Gravitational potential energy is simply the potential energy an object possesses relative to another object due to gravity.
It is expressed as;
[tex]U = mgh[/tex]
Where m is mass, h is height or distance from the other massive object and g is the gravitational field ( [tex]g = 9.8m/s^2[/tex] )
To determine the gravitational potential energy of circus performer, we substitute our values into the expression above.
[tex]U = mgh\\\\U = 50kg\ *\ 9.8m/s^2\ *\ 10m\\\\U = 4900kgm^2/s^2\\\\U = 4900J[/tex]
Therefore, the gravitational potential energy of the circus performer walking on the tightrope above the ground is 4900J.
