An athlete whirls a 6.50-kg hammer tied to the end of a 2.0-m chain in a horizontal circle. The hammer moves at the rate of 1.1 rev/s.

What is the centripetal acceleration of the hammer?
What is the tension in the chain?

What have you tried so far?

a = (v^2)/r is a start
 
1.1 rev/s is not the velocity right?
 
It is, but you must convert to m/s for use in the equation for centripetal acceleration.
 
how do you convert it?
 
(1.1 rev/s)(2piR meters/rev)
