Answer:
[tex]\boxed {\boxed {\sf 98.1 \ Joules}}[/tex]
Explanation:
The formula for potential energy is:
[tex]E_p=mgh[/tex]
where m is the mass, g is the gravitational acceleration, and h is the height.
The mass is 5 kilograms and the height is 2 meters. Assuming this ball is on Earth, then the gravitational acceleration is 9.81 meters per square second.
[tex]m= 5 \ kg \\g= 9.81 \ m/s^2 \\\h= 2 \ m[/tex]
Substitute the values into the formula.
[tex]E_p= ( 5 \ kg )(9.81 \ m/s^2)( 2 \ m)[/tex]
Multiply the first two numbers.
[tex]E_p=49.05 \ kg*m/s^2 (2 \ m )[/tex]
Multiply again.
[tex]E_p= 98.1 \ kg*m^2/s^2[/tex]
[tex]E_p= 98.1 \ J[/tex]
The ball has 98.1 Joules of potential energy.
