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
this is not right.
