For those who love mathemactics!!!

Hi! This post is mainly for those who love mathematics.

 

I think this question that I shown below will prove your talents in Trigonometry and in Mathematics.

 

"The length of a string between a kite and a point on the ground is 68m. If the string makes an angle X with the level ground such that tanX = (15/8), how high is the kite?"

 

The ANSWER is 60M. Thatz the only answer.

i don't know what your schooling is but I study physics at university and there are many others here who study mathematics, physics, chemistry and have already finished your question is really trivial:

sin(arctan(15/8))*68=h where h is the height you seek.

 

Nothing against posting riddles, but they have to be challenging....

Well.. Sanctus, I think you hav tried and answered my question. I really appreciate it. But, The answer that you gave me is absolutely wrong.

So, I think you better giv it another try. Best of Luck.

 

Thank You!!!

I hope this isn't a trick question like you want the height of the kite from the center of the earth or something. Can the problem be solved with just the information you give us?

But, The answer that you gave me is absolutely wrong.

I really don't see where Sanctus went wrong.

 

Of course, there is an alternative method, using proportions and Pythagoras, but neither of the two is actually wrong.

sin(arctan(15/8))*68 = the height is correct

___I'm poor at trig, ;) but I don't like riddles ;) & I fly kites a lot. ;) Unless those trig expresions describe a cantenary, I'd say they're wrong. ;)

___In all my kite flying years, I don't recall ever seeing a kite string take a consistant curve from kite to ground; too many other levels of winds & eddys. If you want the altitude of a kite, forget the length of the string & either use an altimeter attached to the kite or take sightings with a clinograph.

___What kind of kite is it. by the by?

[Qfwfq]

True considerations, T, ;) .

 

Of course, "for those who love mathematics", the only good alternative is the clinograph, providing air isn't too refractive and nearby mountains aren't deviating your plumb line! ;)

___Some further relflection on the dynamics of a kite string which affect how high the kite flys for a given length of string.

 

___The parameters of the string; material, twist, braid, elasticity, water absorption, aerodynamic drag cooeficient, weight per unit length ratio, to name a few.

 

___Parameters of weather; varying wind speed as mentioned above, varying wind direction, decrease in air density with climb in altitude, differing relative humidty at varying levels.

 

___Parameters of the kite; the principle parameter affecting the tension on a kite line aside from the kites surface area, dihedral, material permeability & stiffness etc, is the kite bridle. A static bridle will straighten the kite line if the force on the kite increases, wheras a dynamic (self adjusting) bridle with spill air from the kite & the line stays relatively in the same position.

 

___Any more? :hihi:

strange my answer was wrong but i get 60 meters....which is the correct solution
