The force is an additive quantity allows to find the result for the total force exerted by the two people is:
= 54 N
Newton's second law gives a relationship between the net force, the mass and the acceleration of the body, when the acceleration is zero, this expression is called the equilibrium condition.
∑ F = 0
Where F is the force that is a vector quantity and therefore additive.
They indicate that the two people pull with a force of 23 N and 31 N in the same direction.
Let's calculate.
= 23 +31
= 54 N
In conclusion, using that force is an additive quantity, we can find the total force exerted by the two people is:
= 54 N

Explanation:
It is given that,
Mass of Millersburg Ferry, m = 13000 kg
Velocity, v = 11 m/s
Applied force, F = 10⁶ N
Time period, t = 20 seconds
(a) Impulse is given by the product of force and time taken i.e.
(b) Impulse is also given by the change in momentum i.e.
(c) For new velocity,
Hence, this is the required solution.
