Problem: The sketch shows the top view of a merry-go-round which is rotating clockwise. A child jumps on the merry-go-round in three different ways:  the child lands the same distance from the center. Compare the magnitudes of the final angular momenta of the merry-go-round. I) from the left,  II) from the top, and  III) from the right. For all three cases,  1. LI = LII < LIII 2. LI > LII > LIII 3. LI = LII > LIII 4. LIII > LI > LII 5. LI = LIII < LII 6. LII > LI > LIII 7. LI = LIII > LII 8. LIII > LII > LI 9. LII > LIII > LI 10. LI > LIII > LII

Problem Details

The sketch shows the top view of a merry-go-round which is rotating clockwise. A child jumps on the merry-go-round in three different ways:  the child lands the same distance from the center. Compare the magnitudes of the final angular momenta of the merry-go-round.

I) from the left, 
II) from the top, and 
III) from the right. For all three cases, 

1. LI = LII < LIII

2. LI > LII > LIII

3. LI = LII > LIII

4. LIII > LI > LII

5. LI = LIII < LII

6. LII > LI > LIII

7. LI = LIII > LII

8. LIII > LII > LI

9. LII > LIII > LI

10. LI > LIII > LII
