You already have to momentum of walking forward, and going back and forth are the same distance. If you go back then you would have to stop, turn and walk, but if you go forward you just have to walk.
Answer:

Explanation:
<u>Net Forces and Acceleration</u>
The second Newton's Law relates the net force
acting on an object of mass m with the acceleration a it gets. Both the net force and the acceleration are vector and have the same direction because they are proportional to each other.

According to the information given in the question, two forces are acting on the swimming student: One of 256 N pointing to the south and other to the west of 104 N. Since those forces are not aligned, we must add them like vectors as shown in the figure below.
The magnitude of the resulting force
is computed as the hypotenuse of a right triangle


The acceleration can be obtained from the formula

Note we are using only magnitudes here



The CORRECT answer would be false. They are different and so therefore the answer is false.
