The largest beet root on record had a mass of 18.40 kg. The largest cabbage 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  10 −2m/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?

d is the correct answer
