When throwing the hammer, an Olympian accelerates the hammer
through 5 full rotations. At the beginning of the rotations,
the linear velocity of the hammer is 15 m/s and by the end of
the 5th rotation it is 30 m/s. From the start of the motion to
the release of the hammer (all 5 rotations), it takes 3.7
seconds. The hammer is a 8.25 kg mass at the end of 130 cm
wire.
Calculate the following:
What is the angular velocity of the hammer at the beginning and
end of the rotations?
What is the average angular acceleration during the turns?
At the end of the throw (assuming constant angular
acceleration) what is the centripetal, tangential, and total linear
acceleration of the hammer?
