## Homework Statement

A solid cylinder of weight 50 lb and radius 3.0 inches has a light thin tape wound around it. The tap passes over a light smooth fixed pulley to a 10 lb body hanging vertically in the air. If the plane on which the cylinder moves is inclined 30 degrees to the horizontal, find (a) the linear acceleration of the cylinder down the inclined plane, and (b) the tension of the tabpe, assuming no slippage.

## Homework Equations

[tex]\sum _\tau = I_c\alpha[/tex]

[tex]I_c = \frac{M_c R_0^2}{2}[/tex]

## The Attempt at a Solution

I'm having an issue seeing the relationship linear acceleration and Newton's 2nd law for rotational motion.

[STRIKE]Am I correct in thinking about substituting [tex]\alpha = \omega^2 R[/tex] into the 2nd law, then applying appropriate forces? [/STRIKE]

Edit: See next post
