    Answer:

    13800 N

    Explanation:

    Impulse is the product of average force and time expressed as I=Ft where I is the impulse which results into change in momentum, F is the average force and t is the time of impact. Making F the subject of formula then

    F=\frac {I}{t}

    Substituting I with 13.8 N.s and time, t witg 0.001 s then the average force is calculated as

    F=\frac {13.8 N.s}{0.001}=13800N

    Therefore, the average force is equivalent to 13800 N
