 So, let us see what kind of numerical you can expect. That is out of this only. That will take up as a numerical. You should follow, okay, which you should follow blindly. Don't apply your name, okay fine. I can, I need not do this. I can solve this question without doing this step. But then, I want you to follow these steps even though it is one of the simplest most questions, which you can solve verbally also. What will happen is that when you follow the steps, even for the simple question, difficult question will also be a simple question, okay. So, force yourself to follow all the things that are given to you. It might be given solving problems, okay. So, you will not let, okay, u is this, s is this, t is this, like that. The question from the word format into mathematics. Now, you can do it like two steps, you must have to follow, even though you are doing it for simple question. If you do it for simple question, then only you can do it for difficult ones, okay. If you, if you help yourself to do it for the difficult ones, okay, respectively. If c is the point between a and b, determine the velocity of particle at c. Since it is a midpoint, it is distance x by 2, x by 2. What is the velocity over here? Like this. I want this kind of data to respond. It's your choice of variable. You can take it as u and b also. Then what do you take for c? Anybody got it? It is two-step, two-step solution. Decision is k, okay. As you can, when you solve. Please know, you can't expect, but then a is not even x is not k. You can remove a and x. Is it even just b to y? No. b to square equals to b square plus 2a into x by 2. Anyhow, points. As you can find this equation. Okay. Initial velocity of points, this is my initial and this is my final. Initial velocity doesn't mean that, what is the initial velocity of points? The velocity. This is a into a b1 square. Okay. So I am going to be b1 square. This I have substituted here. The value of a into x plus b2 square by 2. It's just two-step question. Questions. You should get used to this question. Just, I mean, class, the mood concept we lost earlier. Before writing the line. What? Two-fifteen, eight-hundred percent. Nine-hundred percent. From there onwards, what is the displacement? That matters. When acceleration is this. Object has initial velocity u. Acceleration a. Acceleration is a. Okay. Displacement. Yeah. Okay. Please, let us solve. Okay. Alright. So, how it is square? What does? Suppose, I am using that formula as equal to. So, is the answer. Can you calculate? How it is solved? So, here is minus and minus one whole square. We can solve a question without knowing this formula. And it helps to solve quickly. If you know this formula. And that's it. So, till now, nothing.
