A cord connected at one end to a block which can slide on an inclined plane has its other end wrapped around a cylinder resting in a depression at the top of the plane as shown in the figure (Intro 1 figure) . Determine the speed of the block after it has traveled 1.80 m along the plane, starting from rest.
Assume there is no friction.
v =1.6 \rm m/s
Correct
Assume the coefficient of friction between all surfaces is mu = 3.70Ã—10âˆ’2. [Hint: In part B first determine the normal force on the cylinder, and make any reasonable assumptions needed.]

again, I don't see how an answer can be achieved without knowing about the inertia of the cylinder. If it rotates, it gains some of the energy.

the problem dosent say it has a radius of .20 m
