pls answer. .im begging u. .physics help. .how long?

While giving birth ,a mother's uterus contracts and exerts a sudden FORCE of 9 lbs on the baby toward the cervix. The cervix and the walls of the uterus RESIST the motion with an average FORCE of 8.93 lbs on the baby in the opposite direction. If the contraction persists the first 3.8 x 10^-5 miles of the baby's head emerges and the baby is later found to have a WEIGHT of 6 lbs, how LONG does the contraction last?

with solutions please>> tnx

tnx a loT . .
