 Okay, guys, so the question was Clint Barton from the Avengers team is at a terrace of 80 meter high building, okay. So place where Barton is is 80 meter above the ground. Natasha is in action on the road to down the building, fine. So down the building there is a road here somewhere Natasha is in action, fine. Clint dropped his bow and this has to be caught by Natasha. From here the bow were dropped, dropped the word indicate implies that the initial velocity is 0. See it is not thrown, it is dropped, dropped means just left, okay, fine. And has to be caught by Natasha. She is 60 meter from the foot of building, okay. The distance where Natasha is, this is 60 meter. Surely it will drop at the foot of the building. So with what speed she has to run to catch the bow. So now this is a horizontal motion, this is a vertical motion, fine. Based on the vertical motion, can I say that s is equal to ut plus half y plus because falling down. I am taking it as 10, okay, generally for the calculation purposes t square, clear. This is 5 and this is 16. The simplification is that t is equal to 4 seconds. In 4 seconds this bow will fall down. So in order to cover a distance of 60 meter in 4 seconds, clear. Horizontal direction there is no acceleration until and unless taken, there is no acceleration stated or there will not be any acceleration when Natasha will run by uniform speed, clear. So speed is equal to distance upon time, clear. The answer will be 15 meter per second because everything was in meters, fine. Sure. So those who got this as the answer, I have got it correct. I have explained that some have assumed that there is no initial speed given. The word indicate when drop means initial velocity is equal to 0. Thank you very much. Keep enjoying solving the problem. Thank you very much and see you in the next problem soon.
