Taylor Example 4.8. Is my reasoning sound? [closed]
This problem has been giving me all sorts of fits. For one, Taylor states that because the frictional force and normal force are forces of constraint, they produce no work. I'm trying to figure out ...

Final state of a two-block system with friction on a smooth ground
I was working on a modified version of this problem (which I solved):
The modification is as follows:
Consider the following system with two masses, $M$ and $m$, with the length of the body $M$...

Friction on parabola [closed]
A block is released from $x=2, y=4$ on a wire frame with equation $y=x^2$ find its velocity when it passes through origin.
The coefficient of friction between block and wire frame is $k$.
I tried to ...

Does really a spring compresses placed between two blocks when one block is given force on a frictionless surface?
When Spring is placed between two bodies on a frictionless surface it gets compressed when one block is given kinetic energy as told by my physics teacher. But it should not compress as there's no ...

Rolling down an arbitrary hill with friction
I had in mind this physical situation of a point mass rolling down a hill of some arbitrary shape ($y=y(x)$, for instance a parabola about $x=0$), with a peculiar friction force whose "expended work" ...
