An athlete whirls a 7.54 kg hammer tied to the end of a 1.5 m chain in a horizontal circle.

The hammer moves at the rate of 1.51 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?
