    Answer:

    It is Potential and corresponding to

    90

    J

    .

    Explanation:

    Potential Energy is energy stored in the system and ready (potentially) to be changed into, say, Kinetic Energy through movement.

    The general expression for Gravitational Potential Energy is:

    U=mgh

    where:

    mg is the weight; h is the height relative to a certain reference level (the ground in this case) choosen to have zero Potential Energy.

    With your data we get:

    U=3⋅30=90J
