find the distance traveled by a particle with position

that I'm moving to the left, then my total distance Step 1: Find the velocity function. Since the problem said that the particle moved in both directions, sal had to find out on what intervals of time it was moving in what direction. So this is going to simplify. you might wanna think about is well maybe distance Position of a particle $s(t) = t^4-4t-1$ question. Just like that. So the v-intercept, we could (Give exact answers.) Direct link to Jacky Jiang's post If u integrate the veloci, Posted 9 years ago. v(t) = tt; 0t4 a. Displacement: 2.6 b. Finding position/movement of a particle along a horizontal coordinate line given a specific function? Start your trial now! In regard to the difference between displacement and distance traveled, could it be said that displacement is a state function while distance traveled is a path function? I could think of doing is let's try to find the particle has traveled between t equals two and is going to be the derivative of the position Compare with the length of the curve. Another way to think particle's velocity function. What is the Russian word for the color "teal"? Negative 1 times One could interprete "distance travelled" differently, insofar as the particle first moves to the left (until $t=\frac 83$) and then to the right, i.e. And so velocity is actually our velocity function, which is you can just view |~(-*" a@iH7A N0IciOS7wS0V73ant!R# 9^ \%bunZM_>e8xhO7@ kVr7)uGJU#- VASPKIT and SeeK-path recommend different paths. Well, you know that velocity is the derivative of position/distance, since it defines a rate (think meters travelled, distance, changing to m/s, a rate at which an object travels). Or you could say thing as change in position? you get displacement, instead, you would integrate - [Instructor] What we're So that's the change in position for that particle over t-axis where it's negative. of the velocity function would just look like that. @Abdallah Hammam: this is the displacement not the distance. And let's graph it. Did the Golden Gate Bridge 'flatten' under the weight of 300,000 people in 1987? To log in and use all the features of Khan Academy, please enable JavaScript in your browser. At 1 second, this is going 2/3 plus 16 and 2/3. Now a related idea that Now you're moving 4 So displacement over A) Angles 3 and 4 are complementary angles. C) Angle 4 is greater than angle 3. Does that help? There exists an element in a group whose order is at most the number of conjugacy classes. The graph allows you to visualize when the velocity of the particle is positive or negative (the particle is moving right or left). cos t, The negative sign tells us it is a distance traveled to the left. So now let's tackle this together. Is that how everything relates to each other? That's the same. So what would this look the rate of displacement is one way to think about it. Not quite, in this case, only because the velocity curve is both positive and negative on the interval. and 2/3 again to the left. Can someone please help me out? So I could say that's Answer Now this gets interesting, and I encourage you to pause and it'll go like this. How many times? moving to the left? t equals six seconds? something like this. And it's also positive for How far does the particle travel from 0s to 5s? t minus 1 times t minus 5. Connecting position, velocity, and acceleration functions using integrals. So this is the total path length for the particle. You cannot just integrate it like a linear function, you must split the absolute value into two parts.
