$K = m \frac{v^{2}}{2}$ $K=mv^2/2$ .

Solving for $m$ $m$ we find

$m = \frac{2 \cdot K}{v^{2}} = \frac{2 \cdot 9500 J}{{(600 m/s)}^{2}} = \frac{19000 J}{360000 \frac{m^{2}}{s^{2}}} = 0.026 kg$ $m=(2*K)/v^2 = (2*9500"J")/(600 "m/s")^2=(19000"J")/(360000"m"^2/"s"^2)=0.026"kg"$ .

Explanation:

Seems like you have a 26g paper airplane. I'm not even sure if is there a drone as light as this.
