Question: a spinning molecular cloud has decreased in radius by a...

Question details

A spinning molecular cloud has decreased in radius by a factor of 25.00. By what factor has the velocity increased?

Hint : Remember, the formula for angular momentum is L = mvr.

the formula for angular momentum is L = mvr. Try rearranging for v and see how v and r are related.

FYI: 625 was wrong.
