Two identical spools of ribbon are held the same height above the floor. the ribbon from spool a is tied to a support, while spool b is not connected to the support. both spools are released from rest at the same instant. assume that the mass of the ribbon is negligible compared to the mass of the spool. which spool hits the ground first? and at what horizontal position does spool a hit the ground, with respect to the position it is dropped from?

b. a lightning bug, plug of grass, and a worm
