An aluminum rod is designed to break when it is under a tension of 600 n. one end of the rod is connected to a motor and a 12-kg spherical object is attached to the other end. when the motor is turned on, the object moves in a horizontal circle with a radius of 6.0 m. if the speed of the motor is continuously increased, at what speed will the rod break? ignore the mass of the rod for this calculation.
