I'd like to first say that I'm not really sure which forum this is supposed to belong in. This one seems to fit best, but my question may be better in one of the math/physics forums...
I'm planning on going through the resources Chris Hecker recommends in his article Physics References...
Homework Statement
To get used to finding the center of mass of an object, I have decided to start with a uniform density square. The square is centered at the origin. The center of mass should be at the center of the square, and thus at the origin.
When I tried to solve this however, my...
Homework Statement
A coin is off-center on a turntable which is spinning at a constant velocity. The coin is not slipping. From what I have gathered, the radial acceleration of the coin is caused by the force of static friction on the coin. There is no tangential acceleration.

Homework Statement
The solution for the differential equation on this page http://electron9.phys.utk.edu/phys135d/modules/m5/Friction.htm#Drag [Broken] checks out, but I can't figure out how they found it. Both my solution and theirs check out. A couple people I asked for help reached the...
Homework Statement
Note: To make this easier, gravity, air resistance, and friction do not exist in this problem.
Given two boxes which are sitting directly next to eachother, and a force applied to the leftmost box in the rightward direction (straight at the other box), are there any...
When you have a line of 4 boxes without gaps between adjacent boxes, and all of them are at rest, what exact forces are involved when a rightward force is applied to the leftmost box to cause it to move straight into the other boxes? To make this easier, lets assume no gravity, friction, or air...
To help me understand how a force is distributed over multiple connected objects, I have been trying to draw the FBDs of two stacked boxes which are sitting on the ground. I haven't been able to solve the problem however, and looking for the solution with Google did not turn up anything useful...
I am trying to figure out how to correctly model a collision between two objects. My original plan was to get the force of impact and use that to get the result of the collision, but apparently you need the result of collision before you can find the force of impact.
How would I find out...
This is not really a homework/textbook/coursework problem. It's something I ran into while studying physics, and I haven't been able to solve it. The rules seem to say that this is the correct forum for something like this, but I can't be certain. If this is misplaced, please move it to the...
