Answer: Throwing some cargo out of the boa
Explanation:Pushing its mast, Pushing the front of the boat, Pushing another passenger are the forces in internal frame. Forces in the internal frame will not push the boat.
Throwing some cargo out of the boat will create force in external frame of the boat. This external force will push the boat and boat starts moving.
Let the initial velocity of the car be u.
Final velocity of the car (v) = 5.43 m/s
deceleration (a) = - 2.78 m/s^2
Time taken (t) = 2.26 s
Using the first equation of motion:
v = u + at
u = v - at
u = 5.43 + 6.28
u = 11.71 m/s
Let the car's displacement be x.
Using second equation of motion:
x = 26.4646 - 7.0995
x = 19.3651 meters
Hence, the displacement of the car is 19.36 meters
