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

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

Therefore, the average force is equivalent to 13800 N
