An athlete whirls a 7.36 kg hammer tied to
the end of a 1.5 m chain in a horizontal circle.
The hammer moves at the rate of 1.07 rev/s.
What is the centripetal acceleration of the
hammer? Assume his arm length is included
in the length given for the chain.
What is the tension in the chain?

acceleration=w^2*radius
w=1.07*2PI radians/sec
