Question de l’élève

Secondaire 5 • 1a

I'm this question ok find it a bit contradictory. Is it just me or the fact that they ask us to refer to question 1, one can assume the initial distance is at 0 meters. But after seeing the answer key they put - 3.5. is it just me or it's kind of ambiguous? This is regarding question 8.a. chapter 2 UARM.

    Hi !

    There nost be a mistake in the correction since it seems that the object is at rest at first. The first position is then 0. The acceleration is positive so it gives a positive velocity and you can calcultate the displacement with the area under the slope.
