4. The hammer throw is one of the oldest olympic sports. The "hammer" consists
of a metal ball attached by a steel wire to a grip that is spun rapidly in a circle and
released, where contestants aim for maximum distance. Dilshod Nazarov, the
2016 Men's Olympic Gold medalist, won Tajikistan's only gold medal (ever!) with a
throw of 80.71 meters, a horizontal distance. The hammer has a mass of 7.26 kg
and the wire is 1.2m in length.
a) Dilshod's winning throw was in the air for 6
seconds. What was the horizontal velocity when
he released the hammer?
