Thanks! And by the way, a very happy new year to you haru! :D May it bring you many new experiences.

Ohh, the only way I was picturing it was the strings being slackened or maybe a reversal of elastic elongation. :P Too much thought into a simple question.

Homework Statement Homework Equations v=fΛ v=√(T/μ) The Attempt at a Solution I know I'm supposed to make an attempt, but I can make heads nor tails of this. Are they changed in a constant ratioo? Does the tension come into play? The answer given is 0.16m

If we integrate from r2 to r1 we get 1/2m(r1^2 - r2^2) right?

Chevelle probably checked wiki for the moment of inertia of an annulus like I did, haha.

1) The plane had an initial velocity when the pilot was sitting in it. As the pilot jumped backward with a certain momentum, an equal amount was imparted to the plane in the opposite direction, which is the direction of the plane. This final momentum of the plane, divided by the mass of...

Post a picture of your attempt. Even an MS Paint jpeg would do.

You've taken the volume of a solid cylinder.

Try drawing all the components of the forces.

2.48 x 10^-3 if we include the key of the first block, 1.943 x 10^-3 if we don't.

Yeah, does that give you the right answer?

The Kinetic energy after should probably include the KE of the first moving block too.

Same here unfortunately.

What is the given answer and what are you getting?

I said the same result would be produced if you placed two masses of msinθ and mcosθ along the axes at ry and rx distance away. Sorry if my answer was confusing.
