So, the units are gonna be meters per minute per minute. AP CALCULUS AB/CALCULUS BC 2015 SCORING GUIDELINES Question 3 t (minutes) v(t)(meters per minute)0122024400200240220150Johanna jogs along a straight path. 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 we don't know much about, we don't know what v of 16 is. So, at 40, it's positive 150. Johanna jogs along a straight path pdf. So, she switched directions. And so, let's just make, let's make this, let's make that 200 and, let's make that 300. And so, these obviously aren't at the same scale. So, let me give, so I want to draw the horizontal axis some place around here. We go between zero and 40. And then, when our time is 24, our velocity is -220. Voiceover] Johanna jogs along a straight path.

If we put 40 here, and then if we put 20 in-between. 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. Johanna jogs along a straight path meaning. 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. Let me give myself some space to do it. So, our change in velocity, that's going to be v of 20, minus v of 12. And so, then this would be 200 and 100. Well, just remind ourselves, this is the rate of change of v with respect to time when time is equal to 16.

And then our change in time is going to be 20 minus 12. It goes as high as 240. So, if we were, if we tried to graph it, so I'll just do a very rough graph here. When our time is 20, our velocity is going to be 240. Well, let's just try to graph. And so, these are just sample points from her velocity function. So, that is right over there.

And so, this is going to be 40 over eight, which is equal to five. So, v prime of 16 is going to be approximately the slope is going to be approximately the slope of this line. So, when our time is 20, our velocity is 240, which is gonna be right over there. But this is going to be zero. And we would be done. Let's graph these points here. So, if you draw a line there, and you say, alright, well, v of 16, or v prime of 16, I should say. We can estimate v prime of 16 by thinking about what is our change in velocity over our change in time around 16. And so, this is going to be equal to v of 20 is 240. Johanna jogs along a straight path wow. So, they give us, I'll do these in orange. And we see here, they don't even give us v of 16, so how do we think about v prime of 16. And then, finally, when time is 40, her velocity is 150, positive 150. And so, what points do they give us? So, let's figure out our rate of change between 12, t equals 12, and t equals 20.

So, when the time is 12, which is right over there, our velocity is going to be 200. And so, this would be 10. Estimating acceleration. 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, we could write this as meters per minute squared, per minute, meters per minute squared. We see that right over there. 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. So, -220 might be right over there. They give us v of 20. And we see on the t axis, our highest value is 40.

Use the data in the table to estimate the value of not v of 16 but v prime of 16. For 0 t 40, Johanna's velocity is given by. We could say, alright, well, we can approximate with the function might do by roughly drawing a line here. Fill & Sign Online, Print, Email, Fax, or Download. This is how fast the velocity is changing with respect to time. We see right there is 200.

Johanna Jogs Along A Straight Path. For 0

And then, that would be 30. 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. So, that's that point. It would look something like that.

AP®︎/College Calculus AB. Let me do a little bit to the right. For good measure, it's good to put the units there. So, 24 is gonna be roughly over here. So, this is our rate. So, we can estimate it, and that's the key word here, estimate. And when we look at it over here, they don't give us v of 16, but they give us v of 12. But what we could do is, and this is essentially what we did in this problem. 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.
