If we're shown a drawing of a person's velocity and acceleration vectors, a. how do we know whether the person is speeding up, slowing down or moving at constant speed? (Note: Vectors in the “same direction" are parallel, and those in“opposite directions" are anti-parallel. So it´s best to avoid these phrases because we want an answer that encompasses all possibilities, not just parallel and anti- parallel.)
