Calculating Speed of Kite String Release for 120ft Kite Flight

AI Thread Summary
The discussion revolves around a physics problem involving a girl flying a kite at a height of 120 feet while the kite moves horizontally at 10 feet per second. Participants clarify the terminology used in the problem, emphasizing that "height" refers to the vertical distance and the string length represents the direct distance from the girl to the kite. There is some confusion regarding whether the problem is physics or calculus-based. Understanding the relationship between the kite's height, string length, and horizontal movement is essential for solving the problem. Clear definitions and restating the problem can aid in comprehension.

Homework Statement


A girl is flying a kite, which is at a height of 120 feet. The wind is carrying the kite horizontally away from the girl at a speed of 10 feet per second. How fast must the kite string be let out when the string is 150 feet long ?



I came from a non english speaking country. I can't understand question well.

Why not try to restate the problem in your own words? Then maybe we can see where your misunderstanding is.
 
Welcome to Physics Forums.

Is this problem really from a physics class? It looks like a calculus problem.

"Height" refers to the vertical distance that the kite is above the ground.

How long the string is, would mean the distance between the girl and the kite. Assume that the string forms a straight line between the girl and kite.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
