A \(100 \mathrm{~kg}\) football player is moving at \(6.0 \mathrm{~m} / \mathrm{s}\) to the east; a \(130 \mathrm{~kg}\) player is moving at \(5.0 \mathrm{~m} / \mathrm{s}\) to the west. They meet, each jumping into the air and grabbing the other player. While they are still in the air, which way is the pair moving, and how fast?
