I can translate better than google:smile:

The term I use is tangential velocity.Rotational or circular motion may require a minimal linear velocity.For instance, the bare minimum speed necessary to finish a loop. Note: I am unable to provide the exact wording because this problem is written in my mother tongue.

enough linear velocity

I tried to solve it using the work-energy theorem.The work done to make it stand on its one vertex should be equal to the change in its kinetic energy. I am confused what will be the value of radius here? I have seen formula of kinetic energy for rolling of circular objects.Can anyone please...

TL;DR Summary: I think A is an non inertial reference frame.So how can I measure kinetic energy about it? I found a solution to the problem which states that Kinetic Energy about A= (Moment of Inertia about an axis passing through A*Angular Velocity^2)/2+(Mass*Velocity^2)/2 .Thus K=9.5.Can...

Can you describe me the details about that pseudo force please?Did you apply ##mR\alpha## along P or along the center of mass?

The total force acting on the pulley is zero so: F=mg+T1+T2 (1)Analyzing the torque and angular acceleration about the actual axis of rotation, the axle of the pulley, gives: τnet=T1R−T2R=Iα (2)If we analyze about point P, the right edge of the pulley where T1 is applied, we get...
