    Answer:

    Potential Energy at the greatest point = 37.5 J

    Explanation:

    Given :

    Mass is 750 g

    In term of kg :

    Mass is 0.75 kg .

    Velocity ( v ) = 10 m / sec

    We have formula for kinetic energy :

    K.E. = 1 / 2 m v²

    Putting values now :

    K.E. = 1 / 2 × 0.75 × 10 × 10

    K.E. = 1 / 2 × 75 J

    K.E. = 37.5 J

    Since K.E . = P.E.

    Thus potential energy of stone is 37.5 J .
