Conservation of Angular Momentum Video Lessons

# 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 &lt; LIII 2. LI &gt; LII &gt; LIII 3. LI = LII &gt; LIII 4. LIII &gt; LI &gt; LII 5. LI = LIII &lt; LII 6. LII &gt; LI &gt; LIII 7. LI = LIII &gt; LII 8. LIII &gt; LII &gt; LI 9. LII &gt; LIII &gt; LI 10. LI &gt; LIII &gt; 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
