Afigure skater begins spinning counterclockwise at an angular speed of 3.2 π rad/s. during a 4.2 s interval, she slowly pulls her arms
inward and finally spins at 8.8 π rad/s.
what is her average angular acceleration
during this time interval?
answer in units of rad/s^2

4.2 rad/s²

Explanation:

Given:

ω₀ = 3.2π rad/s

ω = 8.8π rad/s

t = 4.2 s

Find: α

ω = αt + ω₀

8.8π rad/s = α (4.2 s) + 3.2π rad/s

α = 4.2 rad/s²

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
