Asked by Abby
An athlete whirls a 6.6 kg hammer tied to the end of a 1.2 m chain in a simple horizontal circle where you should ignore any vertical deviations. The hammer moves at the rate of 1.02 rev/s.
What is the centripetal acceleration of the hammer? Assume his arm length is included in the length given for the chain.
Answer in units of m/s2.
What is the tension in the chain?

change rev/s to radians/sec
centacceleration-masshammer *w^2*rad

For some reason I didn't realize that revolutions/sec was ANGULAR frequency. Thank You!

one revolution is 2 pi radians
so
one Rev/second = 2 pi radians/second
so
one Rev/second = 2 pi radians/second
