If the moment of inertia of the diver in a straight position is 14 kg⋅m2 and in a tucked position is 4.0 kg⋅m2 , by what factor is her angular velocity when tucked greater than when straight?\

required factor of angular velocity is 3.5

Explanation:

given data

I straight = 14 kg.m²

I' tucked = 4 kg.m²

solution

as here by the conservation of angular momentum we get

I straight = I tucked  .................1

I × ω = I' × ω'  

required factor of angular velocity is 3.5

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
