A world champion hammer thrower, rotates at a rate of 3.5 revolutions/sec just prior to releasing the hammer.
a) If the hammer (i.e., the steel mass on the end of the cable) is located 1.4 m from the axis of rotation, what is the radial acceleration experienced by the hammer?
b) What is the centripetal force acting on the 12-kg hammer (i.e., tension in the cable)?
c) What was the linear velocity of the hammer at release?
