Centripetal acceleration experienced by the athlete

Reference no: EM13671682

A hammer thrower rotates at a rate of 2.9 rev/s just prior to releasing the hammer. If the hammer is located 1.4m away from the axis of rotation, what is the centripetal acceleration experienced by the athlete? How much tension (i.e. force) is required to produce this centripetal acceleration if the mass of the hammers 7.5 kg?
