2.47 m/s
Step-by-step explanation:
A girl flies a kite at a height 34 m above her hand.
It is vertical height of kite, 34 m
Let the length of string released be s m
In right triangle using pythagoreous theorem
For s = 60 m ,
Differentiate the equation w.r.t t
Hence, the rate of string letting out 2.47 m/s
