I've heard of radio telescopes before on tv, I think they emit waves and measure how they are refracted/diffracted.
Thanks,

Answer:
3.55kg
Explanation:
K. E = ½mv²
Where m = mass, v = velocity
K. E = 300J
v = 13m/s
Therefore,
K. E = ½mv²
300 = ½ × m × 13²
Multiply both sides by 2
600 = m × 169
Divide both sides by 169
m = 600 ÷ 169
mass = 3.55kg
