Hello, everyone. A particle moving along the line. It's a displacement according to the function, uh, ex ft. Uh, except he is equal to a T squared minus tootie plus four, where X is measured in meters and tease, measured in seconds. But in the average velocity or the time period, A T is equal to 02 I find it from 0 to 2. So the average velocity, um, is just a fancy way of saying to slope. So if you want to find the average velocity from 0 to 2, we're just going to plug. It was going to find this slope. Essentially. So when we plug in, um, well, this little was just why? To minus lie one over x two minutes, x one. In this case, no, uh, that X two is two. And why x one is zero. And I would have to find the corresponding my values. Several good to plug in to into our equation to get why, too. So we get, uh, t squared. So two squared minus two times two. Bless for which is equal to four. Um, so we have four of the top eyes. Why? To um And then for? Why one? We're going to plug in zero, so you get zero squared plus for so is also equal to four. So get four minus four, divided by two minus zero, which is equal to zero. So our average velocity over this time period is going to be equal to zero meters per second. So thank you for watching, and I hope this helps.
