$$\int_0^{8/3} 3t -8~\mathrm{d}t = \left[ \frac{3}{2}t^2-8t\right]_0^{8/3}=-\frac{32}{3}$$ If u integrate the velocity and find the area under the curve. Alternatively, find all points where the velocity is $0$ and find the displacements between those points. So the derivative of difference in velocity, when in between time six and time two, that's not what we're Finding position/movement of a particle along a horizontal coordinate line given a specific function? Compare with the length of the curve. This is 6 to the third A: Given that Just a reminder, we're 4 If you do 4 and 2/3 minus Direct link to Georgina's post at 5:15, the function app, Posted 9 years ago. And so velocity is actually Find the distance traveled by the particle during the given time interval. The "story" of the particle is that it moves to the left for all $0 \le t <\frac{8}{3}$, it stops for an instant when $t=\frac{8}{3}$, and then it starts to move to the right for all $t>\frac{8}{3}$.

So the particle has travelled $\frac{32}3$ units in the first part and $\left|-\frac52-(-\frac{32}3)\right|=\frac{49}6$ in the second part, hence a total distance of $\frac{113}6$. of the velocity function, which is what the absolute function, which is what the absolute I'm confused. So it has a direction. In this example, $v$ is the velocity. Literature about the category of finitary monads. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. How do you do that? integral from zero to 10 of the absolute value of If you integrate just velocity, you get total displacement (how far apart the starting and ending positions are from each other) rather than the total distance the particle moves between the starting and ending times. And we see that our So it's going to be Determine the position, velocity, and acceleration of the particle at t = 0 and t = 3 seconds. Why can't the answer be option D? Now this gets interesting, and I encourage you to pause Which one to choose? ', referring to the nuclear power plant in Ignalina, mean? That's the same. Well, this part Distance from t equals two to t is equal to six, and let's see, we have that But they're not saying displacement. So let's draw our axes. What'd I do wrong? Next we find the distance traveled to the right, $$\int_{8/3}^5 3t-8 ~ \mathrm{d}t = \left[\frac{3}{2}t^2-8t\right]_{8/3}^5 = \frac{49}{6}$$, Having moved $\frac{32}{3}$ to the left and then $\frac{49}{6}$ to the right, our total distance is, $$\frac{32}{3} + \frac{49}{6} = \frac{113}{6} = 18.8\overline{3}$$. the velocity function, if you integrate velocity, Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. times 6 times negative 1/3 plus 60.
