Solving Rotating Frame Problem: Need Help!

AI Thread Summary
The discussion revolves around solving a problem related to a rotating frame of reference, specifically focusing on the acceleration of mass m_a after a catch is removed. It is suggested that the acceleration should equal ω²ra in the non-inertial rotating frame. The participants note that the centrifugal forces acting on the connected masses work in opposite directions. When the masses m_a and m_b are equal and the rope length is twice the radius, the resulting acceleration is determined to be zero. The conversation highlights the complexities of analyzing motion in non-inertial frames.

i am facing problem in attempting the peoblem attached below

if i work in the non inertial frame (the rotating)

shouldn't the acceleration of m_a after the catch is removed

be simply =\omega2ra

thanks in advance

The masses are connected with a rope. The centrifugal forces on them work in opposite direction. If m_a = m_b and l = 2 r_a The acceleration is obviously 0.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
