A 5-kilogram mass is lifted from the ground to a height of 10 meters. The gravitational potential energy of the mass is increased by approximately
A 0.5 J.
B 50 J.
C 250 J.
D 500 J.

For potential energy in joules the formula is

[tex]PE= mgh[/tex]

In which m is the mass in kg, g is the gravitational force [tex]9.8 m/sec^{2} [/tex] , and h is the height above the ground.

[tex]PE= 5*9.8*10=490[/tex]

We round 490 to 500

Therefore the answer is D
