    The correct option is B which is 187,500 N.

    Explanation:

    According to the second law of motion, if a considerable amount of force is exerted on an object of mass, it will produce acceleration in the object.

    F = ma.

    By putting values from question in the above formula:

    F = 250 kg * 750 m/s2

    F = 187,500 Kg. m/s2.

    Kg. m/s2 is equal to 1 newton which is the unit of force.

    Hence the correct option is B which is 187,500 N.

    Use Newton's second law: F=ma

    m = 250kg. a = 750ms-2

    F = 250 x 750 = 187 500N
