Would a speck of dust travelling at 0.9c be enough to destroy an entire planet?

You aren't capable of running the numbers on that yourself, so you will never know.

Would an array of dust traveling that fast be enough?

the mystery will trouble you for your whole life, but you will never bother to learn how to the answer to your question.

Relativistic energy equation is
$ E = mc^2\left(\frac{1}{\sqrt{1-\frac{v^2}{c^2}}} - 1\right) $
Have at it.

You need to learn to translate things into the language of your choice. I suggest Knuth's TAOCP if you don't know how.

No. F=m*a

The spec decelerates to 0 to c when it hits something, but the force is always dependent on the mass. The spec very likely has far, far too low of mass to do any damage. Humanity gets hit by subatomic particles going .9c and above all the time.

TAOCP was already deprecated by TACB back in late 80s usenet, now ask me how I know you’re a help desk monkey

No, it would have to be much larger. The mass of an iceberg, perhaps. Depending on what you consider "destroyed" it might even need to be larger than that.

irrelivant because a spec of dust is not going to have inertia or accuracy to hit the planet
