If two coins are placed on a rotating disc (constant speed), what forces act on the coins, at what direction and in what proportions?
(The coins aren't sliding)
Gravity is one, and the normal force is the one counteracting on that.
But what forces could be expected in a horizontal...
The centripetal force for the particle is F=(mv^2)/R
Could this force be expressed as F = ma, where a is the acceleration in a cylindrical coordinate system?
i.e:
r=R(cosa, sina)
v=Ra'(-sina, cosa)
a=Ra''(-cosa,-sina) <----
Am I way off here?
Does anybody have an approach on this...
Hello,
I've encountered some problems while doing a mechanics project, and was hoping for some help here.
The problem is what follows:
An icecube starts to move at the top of a half spherical building (start velocity 0, no friction, and can be regarded as a particle). What's the icecube's...
