In the mens hammer throw field event, athletes compete to throw a "Hammer" as far as possible. A "Hammer" consists of a ball of mass 7.257 kg attached to a cable of length 1.215 meters. Athletes typically spin the hammer 4 times before releasing. The world record for a hammer throw is 86.74 meters by Yuriy Syedikh of the Soviet Union in 1986.
c. assuming Yuriy Syewingspanh has a mass of 100kg, what is the minimum coefficient of static friction needed by his shoes to keep him from slipping as he releases the hammer?
