Question

A kite is flying at a height of 60 m above the ground. The string attached to the kite is temporarily tied to a point on the ground. The inclination of the string with the ground is 60°. Find the length of the string, assuming that there is no slack in the string.

Answer 1

Let K be the kite and the string is tied to point P on the ground.

In ΔKLP,

`("KL")/("KP") = sin 60°`

`60/("KP") = sqrt3/2`

KP = `120/sqrt3`

KP = `40sqrt3` m

Hence, the length of the string is `40sqrt3` m.
