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...

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...

palaphys replied to the thread Vertical Circular motion- A confusing question.not understanding what you mean by compression. is it stress/ tension?

palaphys replied to the thread Vertical Circular motion- A confusing question.how is it D? not able to get why it is D.. I know that there is going to be projectile motion of the bob. But doesn't the tension in the...

palaphys posted the thread Vertical Circular motion- A confusing question in Introductory Physics Homework Help.Now this question really startled me. We all know that from simple energy conservation, the ball can reach a height of 2l, i.e reach the...

I get the same answer (ignoring the formatting issue noted below). The expression "##V/5R##" is wrong because it actually means ##\frac...
