Explanation:
Where are the questions so that I can deliver a more accurate answer.
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.
