Answer:

#352.8 \ "J"#

Explanation:

Gravitational potential energy is given by the equation,

#"GPE"=mgh#

  • #m# is the mass of the object in kilograms

  • #g# is the gravitational acceleration, which is approximately #9.8 \ "m/s"^2#

  • #h# is the height of the object in meters

And so, we got:

#"GPE"=12 \ "kg"*9.8 \ "m/s"^2*3 \ "m"#

#=352.8 \ "J"#
