i have two questions that i need help understanding
1a. Homework Statement
A majorette takes tow batons and fastens them together in the middle at right angles to make an "x" shape. Each baton was 0.6m long and each ball on the end is 0.50kg. (Ignore the mass of the rods.) What is the moment of inertia if the arrangement is spun around an axis formed by one of the batons?
2a. Relevant equations
I=(1/12)ML^2
3a. The attempt at a solution
Not sure how to apply the equation to the problem. And what does it mean when n the arrangement is spun around an axis?_______________________________________________
1b. Homework Statement
A tether ball is attached to a pole with 4.0m rope. It is circling at 0.20 rev per second. As the rope wraps around the pole it shortens. How long is the rope when the ball is moving at 6m/s
2b. Relevant equations
not sure
but .20 rev/sec = 1.26 rads/sec
3b. The attempt at a solution
not sure what to do.. what equations should i be focusing on?
