A string attached to an airborne kite is maintained at an angle of 41 degrees with the horizontal. If a total of 152 m of string is reeled in while bringing the kite back to the ground, what is the horizontal displacement of the kite in the process

Respuesta :

Answer:

The  horizontal displacement is  [tex]Adj = 114.71 \ m[/tex]

Explanation:

From the question we are told that  

    The  angle at which the string is maintained is  [tex]\theta = 41 ^o[/tex]

      The length of string reeled in is  [tex]l = 152 \ m[/tex]

     

Using the SOHCAHTOA formula

   We have that the hypotenuse(Hyp) is  l  =  152

Hence the  horizontal displacement of the kite  which is the Adjacent(Adj)  can be evaluated as  

     [tex]cos \theta = \frac{Adj}{Hyp }[/tex]

substituting values

     [tex]cos(41) = \frac{Adj}{152}[/tex]

=>   [tex]Adj = 114.71 \ m[/tex]
