    K. E = 1.13 * 10^5 J

    When compared to;

    K. E = a. bc X 10^d J

    We can observe that;

    a = 1

    b = 1

    c = 3

    d = 5

    Explanation:

    Given;

    Mass of rhinoceros m = 1000kg

    Velocity v = 15m/s

    The kinetic energy of the body at this speed is;

    K. E = 0.5*mv^2 ... 1

    Substituting the values of m and v into equation 1;

    K. E = 0.5*1000*15^2

    K. E = 112500 J

    K. E = 1.13 * 10^5 J

    When compared to;

    K. E = a. bc X 10^d J

    We can observe that;

    a = 1

    b = 1

    c = 3

    d = 5
