Hi Delphi,
Thanks for your reply. Your deduction is right, but we have to express the coefficient in terms of a0 (the acceleration of the plank) and not just a (the acceleration of the cylinder ON the plank - which is due to rotation)
1. Homework Statement
This is a relatively simple problem in classical mechanics, but my attempt at a solution seems to conflict with the result my teacher announced.
The problem is as follows:
A homogeneous cylinder with mass M and radius R lies at rest on a plank. The plank is then...
A car is driving along a curved path (with a given radius) that is angled relative to the surface of the earth. The speed is of such magnitude that the friction force between car and road has a component directed downward the incline, however the friction does not have its maximum value. (So...
