--K-
3 m/s
Baelish was too shy to give his gift to his friend, Sansa, so he made a contraption out of a 1 m-
radius gear L, a 1.2 m-radius gear I and a 0.5 m-radius cylindrical spool of rope K. The spool K was
glued and is concentric to gear I.
He skillfully rotated gear L causing it to have a constant angular acceleration. Starting from rest,
gear Lrotated a total of n/3 radians right before the speed of box E became 3 m/s. At this instant,
a. What is the ratio between the angular velocities of gear L and I, wi and wi?
