    Answer:

    6,653.34 J

    Explanation:

    Kinetic energy can be found using the following formula.

    KE=\frac{1}{2} mv^2

    where m is the mass in kilograms and v is the velocity in m/s.

    The object is 108 kilograms and is moving at a speed of 11.1 m/s. Therefore, the mass is 108 kg and the velocity is 11.1 m/s.

    m=108 kg

    v=11.1 m/s

    Substitute these values into the formula.

    KE=\frac{1}{2}*108*11.1^2

    Evaluate the exponent first. 11.1^2 is the same as 11.1*1.11, which is equal to 123.21

    KE=\frac{1}{2} *108*123.21

    Multiply 108 and 123.21

    KE=\frac{1}{2}*13306.68

    Multiply 1/2 and 13306.68

    KE=6653.34

    The kinetic energy of the object is 6,653.34 Joules (kg m2/s^2)
