Answer:

#3.675 \ "J"#

Explanation:

Gravitational potential energy is given by the equation:

#"GPE"=mgh#

where #m# is the mass of the object in kilograms, #g# is the gravitational acceleration, which is around #9.8 \ "m/s"^2#, and #h# is the height that the object is standing on in meters.

So, we get:

#"GPE"=1 \ "kg"*3/8 \ "m"*9.8 \ "m/s"^2#

#=3.675 \ "kg m"^2"/s"^2#

Remember that #1 \ "J"=1 \ "kg m"^2"/s"^2#, and so we got:

#=3.675 \ "J"#
