And let's see, we can see this choice right over there, and that's what we would pick. This first option, v of seven, that just gives us our velocity at time seven, or exactly at seven seconds. Or another way is our rate of change of displacement at seven seconds, so that's not what we want. This one right over here, you have your position at t equals two, but then you have your change in position from t equals zero to t equals seven. So this doesn't seem, this isn't right. And this is your position at time two plus your v prime, the derivative of velocity, is the acceleration, plus your acceleration at time seven. So that's definitely not gonna give you the particle's position, so we like that second choice.
