1. ### Finding the velocity change before colliding

Homework Statement Two identical blocks of mass M are tied with a mass-less string of length L. If the string is pulled with a force F right at the midpoint of string L, the blocks will move towards each other. What will the velocity be when the blocks collide. The blocks start from rest and...
2. ### Understanding centrifugal force

how would the same case be analyzed from the rotating frame of reference
3. ### The classic 'stone at the end of a thread problem'

Dear experts, when a a stone at the end of the string is rotated with a high speed so that the string is suspended making zero degrees with the plane of the ground, how do we analyze the system from the rotating frame.
4. ### Understanding centrifugal force

Is a plastic collision possible if there is no frictional interaction to reduce the kinetic energy?
5. ### Understanding centrifugal force

Still, from an inertial observer, assuming a friction less Ship wall vs Mike interaction, what i understand is that there is no element of rotational effect on him. Mike never seem to execute a circular motion, in any case. or even in sync or out of sync with the ship wall. And it doesn't seem...
6. ### Understanding centrifugal force

Sir, i think i get u on this. Please tell me if i am wrong. If there is no frictional interaction, Its just like a collision. During that collision, Mike gets some momentum imparted to him. and he should move in a straight line in the direction of the final momentum(his initial plus what the...
7. ### Understanding centrifugal force

I understand the fact that in the absence of frictional force to provide a tangential force, there is no torque on the body about the center of the spinning ship. In that case, could we still find out a clear idea about how 'mike' will move as observed from an inertial frame. Purely under the...
8. ### Understanding centrifugal force

So is it correct that , one must exclude the tangential force, if we assume that the wall is friction-less. In which case, only the normal reaction is felt by the body. in both cases, how will the body be affected. the normal reaction will possibly give the body the centripetal force required...
9. ### Understanding centrifugal force

Thank you Sir, and i really appreciate your guidance, So, i believe that from an inertial frame, an observer will find no effect what so ever on an aloft body, unless it strikes on the wall. When it strikes on the inner walls, it recieves a normal reaction 'radially inward' which i think is...
10. ### Understanding centrifugal force

It would be highly helpful if i could understand it from both frames. Thank You.
11. ### Understanding centrifugal force

Dear Experts, I believe that we use the concept of Pseudo Forces, to analyze mechanics within an accelerating frame of reference. Pseudo force seems to be a 'correction' in acceleration provided to all the points that are not riveted to the accelerating frame of reference. And centrifugal force...
