Asked by Ethan
A figure skater begins spinning counterclockwise at an angular speed of 4.6π rad/s. During a 4.6s interval, she slowly pulls her arms inward and finally spins at 7.6π rad/s.
What is her average angular acceleration
during this time interval?
Answer in units of rad/s^2.

ω2 = ω1 +ε•t,
ε = (ω2 - ω1)/t=
=(7.6π -4.6 π)/4.6=2.05 rad/s^2
ε = (ω2 - ω1)/t=
=(7.6π -4.6 π)/4.6=2.05 rad/s^2
