Add the KE increase and the work done against friction.
The final velocity is twice the average, or 3.0 m/s
The final KE is (1/2)*25*3^2 = 112.5 J
The friction work done is 6*3.8 = 22.8 J
hope this is correct
<h2>Right answer: 8 m</h2><h2 />
When two waves propagate in the same medium, in the same or opposite direction, they <u>overlap (superposition</u>), that is, the individual waves are added producing a resultant wave. When the superposition of the waves occurs, they continue to advance after the encounter happens, conserving their properties, such as amplitude, frequency, wavelength and speed.
In this case, we have two water waves travelling in opposite directions with <u>differente amplitude</u>, when both waves encounter each other, at that moment the amplitude of the resultant wave is the sum of both, that is:
5m + 3m = 8 m
Therefore, the correct option is D
