1. The problem statement, all variables and given/known data If an air parcel 2000m from a tornado center has a tangential velocity of 10 m/s, what is the resultant tangential velocity if the parcel is 100m from the tornado center. 2. Relevant equations v = rω, where r = radius, and ω = angular velocity ω = v/r 3. The attempt at a solution I understand that the tangential velocity of the air parcel should be much faster as radius drops. But how am I supposed to calculate tangential velocity of it requires the calculation of angular velocity which requires velocity. I'm really lost.
