    Answer:

    31.86

    Explanation:

    From the law of conservation of linear momentum, energy can neither be destroyed nor created but can only be transformed from one state to another. Kinetic energy in this case is converted to potential energy

    0.5mv^{2}=mgh

    Making h the subject of the formula then

    h=\frac {v^{2}}{2g}

    Here m represent mass, g is acceleration due to gravity whose value is taken as 9.81, h is the height and v is the velocity. Substituting the given values then

    h=\frac {25^{2}}{2\times 9.81}

    h=31.86 m
