Canon!ArthurWeasley isn't very knowledgeable, but he at least had an interesting in electrical power, heavy-than-air non-magical flight, and chemical fueled engines. I think we can expect him to be of similar intelligence or smarter in MoR.

I don't think so, per chapter 61:

Madam Bones's voice continued. "We brought in Arthur Weasley from Misuse of Muggle Artifacts - he knows more about Muggle artifacts than any wizard alive - and gave him the descriptions from the Aurors on the scene, and he cracked it. It was a Muggle artifact called a rocker, and they call it that because you'd have to be off your rocker to ride one. Just six years ago one of their rockers blew up, killed hundreds of Muggles in a flash and almost set fire to the Moon. Weasley says that rockers use a special kind of science called opposite reaction, so the plan is to develop a jinx which will prevent that science from working around Azkaban."

...

"Severus?" the old wizard said. "What was it actually?"

"A rocket," said the half-blood Potions Master, who had grown up in the Muggle town of Spinner's End. "One of the most impressive Muggle technologies."

It seems pretty clear from chapter 61 that MOR!ArthurWeasley knows precious little about the muggle world.
