And then, when our time is 24, our velocity is -220. They give us v of 20. Let me do a little bit to the right. So, we literally just did change in v, which is that one, delta v over change in t over delta t to get the slope of this line, which was our best approximation for the derivative when t is equal to 16. So, this is our rate. Johanna jogs along a straight pathfinder. And so, this would be 10. And so, this is going to be equal to v of 20 is 240. And when we look at it over here, they don't give us v of 16, but they give us v of 12. AP CALCULUS AB/CALCULUS BC 2015 SCORING GUIDELINES Question 3 t (minutes) v(t)(meters per minute)0122024400200240220150Johanna jogs along a straight path. So, if you draw a line there, and you say, alright, well, v of 16, or v prime of 16, I should say.

Johanna Jogs Along A Straight Pathfinder

So, we could write this as meters per minute squared, per minute, meters per minute squared. So, when the time is 12, which is right over there, our velocity is going to be 200. Johanna jogs along a straight pathologies. And we see here, they don't even give us v of 16, so how do we think about v prime of 16. So, at 40, it's positive 150. Let's graph these points here. For 0 t 40, Johanna's velocity is given by. Well, let's just try to graph.

And then our change in time is going to be 20 minus 12. They give us when time is 12, our velocity is 200. For good measure, it's good to put the units there. We see right there is 200. This is how fast the velocity is changing with respect to time. Johanna jogs along a straight path lyrics. AP®︎/College Calculus AB. For zero is less than or equal to t is less than or equal to 40, Johanna's velocity is given by a differentiable function v. Selected values of v of t, where t is measured in minutes and v of t is measured in meters per minute, are given in the table above. Estimating acceleration. But what we could do is, and this is essentially what we did in this problem.

So, -220 might be right over there. Let me give myself some space to do it. Use the data in the table to estimate the value of not v of 16 but v prime of 16. So, she switched directions. So, v prime of 16 is going to be approximately the slope is going to be approximately the slope of this line. And we see on the t axis, our highest value is 40. So, if we were, if we tried to graph it, so I'll just do a very rough graph here. Fill & Sign Online, Print, Email, Fax, or Download. But what we wanted to do is we wanted to find in this problem, we want to say, okay, when t is equal to 16, when t is equal to 16, what is the rate of change? So, 24 is gonna be roughly over here. Now, if you want to get a little bit more of a visual understanding of this, and what I'm about to do, you would not actually have to do on the actual exam. And so, then this would be 200 and 100. And then, that would be 30. We could say, alright, well, we can approximate with the function might do by roughly drawing a line here.

So, our change in velocity, that's going to be v of 20, minus v of 12. It goes as high as 240. So, we can estimate it, and that's the key word here, estimate. That's going to be our best job based on the data that they have given us of estimating the value of v prime of 16. We go between zero and 40. It would look something like that.

And so, these are just sample points from her velocity function. So, the units are gonna be meters per minute per minute. So, when our time is 20, our velocity is 240, which is gonna be right over there. We see that right over there. So, let's say this is y is equal to v of t. And we see that v of t goes as low as -220.

And then, finally, when time is 40, her velocity is 150, positive 150. Well, just remind ourselves, this is the rate of change of v with respect to time when time is equal to 16. So, they give us, I'll do these in orange. And so, what points do they give us? If we put 40 here, and then if we put 20 in-between. But this is going to be zero. So, that's that point. So, let's figure out our rate of change between 12, t equals 12, and t equals 20. And so, this is going to be 40 over eight, which is equal to five. And we would be done. And so, let's just make, let's make this, let's make that 200 and, let's make that 300.
