    Answer:

    23.9m

    Explanation:

    step one:

    This problem is on energy.

    we can proceed by using the expression for potential energy to solve for height h

    we know that

    PE=mgh

    given that

    mass m= 5kg

    PE= 1176 joules

    step two:

    we can substitute our data and find h

    1176= 5*9.81*h

    1176=49.05h

    step three:

    divide both sides by 49.05 we have

    1176/49.05=h

    h=23.9 m

    The height of the tree is 23.9m
