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.
As the length increases, resistance increases, as a result current decreases.

Velocity is displacement/time
(Displacement is the overall change in distance)
So you’ll want to divide 200 by 25, which should give you:
8 m/s
