Answer:
F = 2349.6 N
Explanation:
We can solve this exercise using the relationship of momentum and momentum
     I = Δp
     I = F t
As the woman accelerates at a distance of 29.1 m to go from rest to 56.8 m / s, we can use the kinematics to find the acceleration
    v² = v₀² + 2 a x
    v₀ = 0
    a = v / 2x
    a = 56.8 2/2 29.1
    a = 55.43 m / s²
Let's look for the time you need to get this speed
   v = v₀ + a t
   t = v / a
   t = 56.8 / 55.43
   t = 1,025 s
Let's clear the average force momentum from the momentum
   F t = m v- m v₀
   F = mv / t
   F = 42.4 56.8 / 1.025
   F = 2349.6 N
