Sagot :
The gravitational potential energy of Sara at the given height is 10594.8J.
Given the data in the question;
- Mass of Sara; [tex]m; = 60kg[/tex]
- Distance from ground; [tex]h = 18m[/tex]
- Acceleration due to gravity; [tex]g = 9.81m/s^2[/tex]
- Gravitational potential energy; [tex]U = \ ?[/tex]
Gravitational Potential Energy
Gravitational potential energy is the potential energy an object with mass posessses relative to another object with mass due to gravity.
It is expressed as;
[tex]U = mgh[/tex]
Where m is mass, h is height and g is acceleration due to gravity.
To determine the gravitational potential energy of Sara, we substitute our given values into the expression above.
[tex]U = mgh\\\\U = 60kg * 9.81m/s^2 * 18m\\\\U = 10594.8kgm^2/s^2\\\\U = 10594.8J[/tex]
Therefore, the gravitational potential energy of Sara at the given height is 10594.8J.
