Hello there. Hope you're having a fantastically awesome date today. We're gonna be selling this equation. Here were D is equal a cube over C B squared and we have some values here. So a is equal. Denying 0.7 meters B is equal to 4.2 seconds C is equal to 69 meters per second. Regan. Right, That has me just for a second like that with the slash their way that I like to write It is meters per second, Um, because that makes the map with the units nicer for me, but you can do whatever makes you happy. So before you start just plugging in all of these values into the equation, um, that will give us the right the miracle answer boat. Beyond that, we really want the right units, and I answer that is a very important thing. As you get further and further along in physics to goto, make sure you have the right units in your answer. So we're gonna, um, not only write down the numbers, but also the units here It's 1.7 meters huge over 69 meters per second times 4.2 seconds squared all right. And so began. Uh, looking all these numbers, we're gonna calculate all these numbers right here, and then we'll worry about the units. So 9.7 cubed over 69 times 4.2 squared is going to equal zero point 75 And we still want those units right there. So our units are gonna be meters huge. So I should write this a little bit different in these were pool. If we'd be a little more intuitive here. All right. As meters cute over meters for a second times. Seconds squared. All right, so this will cancel. All right? Here. Her this wall, That's what we'll simplify out a little bit. We're gonna get your 0.75 uh, meters Will can swell a little bit. We'll get meaner, squared, and the per seconds and the second squared or Ginette simplify a little bit. They're gonna reduce down a bit. We're gonna be left with meters squared purse. I can't write it this way for the final answer. All right. And there you have it. Hope that was hopeful in good luck
