One of the events at the Olympic Games is the "hammer throw". Confusingly, the "hammer" is not actually a hammer but rather a metal ball of mass 7.26 kg attached to a wire of length 1.22 m. Athletes participating in this event accelerate the hammer by whirling themselves, and the "hammer", around in a circle. Once the hammer attains its maximum speed (the exact value of which will depend on the athlete's ability), it briefly undergoes uniform circular motion before it is released and goes flying off somewhere, hopefully not into a crowd of spectators. a. The diagram below shows the path of the hammer as it undergoes uniform circular motion in a clockwise direction before being released. Copy the diagram onto a piece of paper or your tablet and draw some labelled arrows at point P to indicate the direction of the: i. Instantaneous velocity of the hammer. i. Instantaneous acceleration of the hammer. Suppose an athlete whirled the hammer through 2 complete revolutions at constant speed in a time of 1.50 seconds and that, during this time, the wire was approximately horizontal. b. Find the period of the hammer. c. Find the speed of the hammer. d. Find the centripetal acceleration of the hammer. e. Find the force exerted by the competitor on the hammer.
