(II) A wooden block is cut into two pieces, one with threetimes the mass of the other. A depression is made in bothfaces of the cut, so that a firecracker can be placed in it withthe block reassembled. The reassembled block is set on arough-surfaced table, and the fuse is lit. When the firecrackerexplodes inside, the two blocks separate and slide apart.What is the ratio of distances each block travels?
