palaphys replied to the thread Angular Momentum- Conserved or not?.ok that makes sense. but I have a question. IF there was no external torque (hypothetical) then is it valid to conserve momentum as I... -
palaphys replied to the thread Angular Momentum- Conserved or not?.I have another question: If angular momentum is conserved, then it would be conserved in all directions. But in the horizontal...

palaphys posted the thread Angular Momentum- Conserved or not? in Introductory Physics Homework Help.Consider the diagram shown above. I came up with two ideas to solve this: i) I do not see any external torques about the vertical axis...

palaphys replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.so are you implying, that the value of F I got using force balance, IS a valid value for some a force to get the block moving? but it's...

palaphys replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.but when velocity is maximum, there is a momentary equilibrium, isn't it? this means forces at that point of time will be balanced. is...

palaphys replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.why is this? why not the eqb. position?

palaphys replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.When the acceleration is maximum, the velocity will be zero, and vice verca. I'm aware of this. But how is it going to help in this case?

palaphys replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.Well, force balance leads to the answer: ##F= μg(m_1 +m_2)##using work done (energy balance equation) leads to ##F= μg(m_2 + 2m_1)/2##...

palaphys replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.When F is large enough to move m1, m1 will start with some acceleration, such that F>kx+friction where x is the elongation in the...

palaphys posted the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring in Introductory Physics Homework Help.The diagram above describes the situation. Say the spring constant is k. The main goal will be to apply the condition that when the...

Like.
Your correction repeats the mistake! You mean ##\arccos (\frac 23)## to the vertical - as you correctly show in your diagram. A... -
palaphys replied to the thread Vertical Circular motion- A confusing question.EDIT- yes, I meant to say that it is ##\arccos (\frac 23) ## with the vertical

palaphys replied to the thread Vertical Circular motion- A confusing question.Yes, this is my understanding Here is my working: yes, I meant to say that it is ##\arccos (\frac 23) ## with the horizontal. thanks...

palaphys replied to the thread Vertical Circular motion- A confusing question.okay, so you are saying that the string can only reach the top slack, with the given speed in the question, that too in a hypothetical...
