A figure skater begins spinning counterclock- wise at an angular speed of 4.6 7 rad/s. Dur-
ing a 4.2 s interval, she slowly pulls her arms
inward and finally spins at 7.3 7 rad/s.
What is her average angular acceleration
during this time interval?
Answer in units of rad/s.

Angular acceleration,

Explanation:

Given that,

Initial angular velocity,

The final angular velocity,

Time, t = 4.2 s

We need to find her average angular acceleration  during this time interval. Acceleration is the rate of change of velocity. So,

So, her average angular acceleration is .

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.
