2. The largest beet root on record had a mass of 18.40 kg. The largest cab-
bage on record had a mass of 56.20 kg. Imagine these two vegetables
traveling in opposite directions. The cabbage, which travels 5.000 m/s to
the left, collides with the beet root. After the collision, the cabbage has a
velocity of 6.600 x 102 m/s to the left, and the beet root has a velocity of
10.07 m/s to the left. What is the beet root's velocity before the perfectly
elastic collision?
