A student athlete is participating in the hammer throw. The student rotates in uniform circular motion with the mass rotating 2.3 m away from the center of rotation. Refer to the information and diagram above. The University Interscholastic League (UIL) is considering adding an event that increases the length of the chain, doubling the distance from the athlete to the mass. By what factor will the acceleration of the ball change if the speed remains unchanged?
