here is a physics

This has absolutely nothing to do with anything ever, but I just want to share the most bizarre problem I have ever seen...

A pendulum swinging on a rocket accelerating in outer space, beyond significant gravitational influence from any celestial body, has a length of 10.0 cm and a period of 0.400 s. What is the acceleration of the rocket?

I just think it's really odd that they tell about the pendulum, then ask about the rocket.

p.s. yes I've figured it out.

Outer space implies no external forces, assume cord is rigid.

Assuming the rocket is orbiting the central point:
cord length and period give you tangential velocity, use a(cent) = v^2/r to calculate centripetal acceleration. Rocket can be assumed to have accelerated rocket to this velocity but is otherwise negligible.

Assuming it's rocking like a pendulum
same thing as any other pendulum problem, just replace 'g' with an arbitrary rocket acceleration that fits the cord parameters. Rocket is a framing device to explain the arbitrary acceleration.

I've seen weirder (momentum balance with snowballs wars on frictionless sleds, anyone)?
