 So, we will be taking missionaries questions, different topics of motion in 2D and we will try to solve that. Right now I will take stop talking, right now I will take means level questions. So, last one hour I will be taking here in advance for the questions. Sign 2 theta is lowest for which of these vectors? Sign theta could be minimum, what about sign 2 theta, that also? See what, what is the air resistance? The body gets so double, what? Say, you have something? Yes, I have something. Sixth one, right, go to the next question. 2 sin theta cos theta, I need to find the related h1, h2 and r. So, if I square r, r square will be 4 times u to the power 4 sin square cos square g square. So, u square sin square theta by 2g is h2, u square cos square theta by 2g is h2. So, I can say that r square and sin square theta by g is h1 and also c. To solve both of them. How many of you got 7th question? The first one. How much it is? D. D, the 7th question, learnt out. So, u is 20, you can substitute the values of g, u and theta here and you can taste the coefficients. So, the range is 3 seconds, understanding how to solve is more important than getting the answer. Because the question will be different.
