Hungarian Adrian Annus won the gold medal for the hummer throw at the 2004 Olympics in Athens with a winning distance of 83.19 meters*.The event consists of swinging a 16 -pound weight attached to a wire 190 centimetres long in a circle and then releasing it. Assuming his release is at a 45 ∘ angle to the ground, the hammer will travel a distance of v 0 2 g metres, where g = 9.8 metres/second 2 and v 0 is the linear speed of the hammer when released. At what rate (rpm) was he swinging the hammer upon release? *Annus was stripped of his medal refusing to cooperate with postmedal drug testing.
