In the field event known as the hammer throw, an athlete spins a heavy mass in a circle at the end of a chain. When the athlete lets go of the chain, the mass flies off in a parabolic arc; the winner is the one who gets the maximum distance. For male athletes, the hammer is a mass of 7.30 kg at the end of a 1.20 m chain. A world-class thrower can get the hammer up to a speed of 29.0 m.s-1. If an athlete swings the mass in a horizontal circle centered on the handle he uses to hold the chain (figure 2 below), what is the tension in the chain at this maximum speed? Include the unit for tension in your answer
