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 = 3.70×10−2. [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

I regret that I cannot figure out the situation from you verbal description. What you have to do is calculate the acceleration rate a, up the incline, from the information available. It willequal the net force up the incline divided by the mass. Assume the mass M will cancel out if you do the problem correctly, since they do not tell you what M is.

The speed of the block after traveling a distance X will be sqrt(2aX)

problem is that i already used that for velocity (same answer) and it's not unfortunately not the right answer.
