Homework Help: physics incline

Posted by andy on Friday, May 22, 2009 at 3:39pm.

A cord connected at one end to a block which can slide on an inclined plane (incline 27 degrees) has its other end wrapped around a cylinder resting in a depression at the top of the plane (and the other angle at bottom is not a right angle, but 58 degrees). Determine the speed of the block after it has traveled 1.20 m along the plane, starting from rest.

A)assume no friction

B)Assume the coefficient of friction between all surfaces is mew = 3.7010−2. [Hint: In part B first determine the normal force on the cylinder, and make any reasonable assumptions needed]

I just have no idea to set it up with the cylinder there
