Select the correct equations that show that the gravitational potential energy of a 1000-kg boulder raised 6 m above ground level is 60,000 J. (You can express g in units of N/kg because m/s2 is equivalent to N/kg.)

Answer:

[tex]U = mgh[/tex]

Explanation:

The gravitational potential energy of an object is defined as:

[tex]U=mgh[/tex]

where

m is the mass of the object

g is the gravitational acceleration

h is the height of the object above a reference level (usually, the ground)

For the boulder in the problem,

m = 1000 kg

g = 10 N/kg

h = 6 m

Substituting,

[tex]U=(1000)(10)(6)=60,000 J[/tex]
