Homework Help: Physics

Posted by Mary on Tuesday, March 13, 2007 at 8:05pm.

A gymnast is performing a floor routine. In a tumbling run she spins through the air, increasing her angular velocity from 3.00 to 5.75 rev/s while rotating through one-half of a revolution. How much time does this maneuver take?

Divide 0.5 revolutions by the average angular velocity (4.38 rev/s). The answer will be in seconds.

Thanks. Is it possible for you to check the three questions i've posted earlier? I am having a problem with them. Thanks again!

Can you please explain how you got 4.38rev/s?

avg= (final+initial)/2= (3+ 5.75)/2=4.38



Thanks!
