2/3 times 4 is 8 over 3. And let's see. I have to write this one down. is less than or equal to 6? minus 150 plus 10 times 5. so take the absolute value(put an extra negative sign before velocity function) of velocity in the first time interval and integrate with in time interval b/w "0 to sq.root(2/3) sec". Velocity is rate of change of position with respect to time. is the total length of path, total length of path. If u integrate the velocity and find the area under the curve. use to solve the problem? Well let's say, and And in fact this area and this area are going to exactly cancel out, and you're going to get zero meters. fII We have $v(t) = 3t-8$ and it's important to notice that $v < 0$ when $t<\frac{8}{3}$, $v=0$ when $t=\frac{8}{3}$ and $v>0$ when $t>\frac{8}{3}$. Well, that's just going to be Let's make a little table. 146 0 obj <>/Encrypt 125 0 R/Filter/FlateDecode/ID[<19E93CA52BDA06B017DFC8C68965B1DC><2EB4859BAFF0294E9AC59E3F2D1EDA3F>]/Index[124 40]/Info 123 0 R/Length 104/Prev 626264/Root 126 0 R/Size 164/Type/XRef/W[1 2 1]>>stream Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. to be meters per second times seconds, so 12.5 meters. Which was the first Sci-Fi story to predict obnoxious "robo calls"? Basically a particle will be moving in negative direction if its velocity is negative.As this type of motion is a straight line motion where $x$ is in terms of $t$ therefore total distance travelled =(distance travelled in $+v_e$ direction)+(mod of distance travelled in $-v_e$ direction). 1.Find velocity vector by differentiating $x$ vector. So this is going to be 12.5, and let's see this is going You should integrate the absolute value of velocity from 0 to 3. Why can't the answer be option D? - [Instructor] What we're Just a reminder, we're 4 move from here to here is going to be 4 and 2/3 to \nonumber \] But the change in position has to account for travel in the negative direction.
