Homework Statement the problem is: A 3.0 m diameter merry go round with rotational inertia 120kgm^2 is spinning freely at 0.50 rev/s. Four 25kg children sit suddenly on the edge of the merry go round. a) Find th new angular speed, and b) detrmine the total energy lost to friction between the...

hi guys I am having a problem with a physics problem. the question is about a seesaw that has two masses, m_1 and m_2 at each end of the seesaw. the length of the seesaw is L, so each mass is a distance L/2 from the pivot (center). i answered the question for what the Inertia was for a...
