' (30 Points) Consider the system below; 77“:
A disk of radius R is pinned to a wall at center. The block and disk have the same mass (m). The middle cylinder is massless and has a radius R‘ which is smaller then R. It may rotate without
friction. The vector g points in the direction of gravity. Below is a side-view. points) 2) How long does it take for the block to fall a height h? (10 points) Consider the system below: A disk of radius R rolls down an inclined plane. The center of mass has an instantaneous velocity
of V=V£ . 3) In the reference frame centered at point 0, what is the instantaneous velocity (Magnitude and
Direction) at point? and Q? (10 Points) < ...
