    Answer:

    E = 15680 J

    Explanation:

    We have,

    Mass of Danielle is 80 kg

    He is at the top of hill at a height of 20 m

    As she slides down at the bottom of the hill, its potential energy gets converted to its kinetic energy. So, the kinetic energy at the bottom of the hill is :

    E=mgh\\\\E=80\times 9.8\times 20\\\\E=15680\ J

    So, she will have 15680 J of kinetic energy at the bottom of the hill.
