An aluminum rod is designed to break when it is under a tension of 242 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.An object moves in the eastward direction at constant speed. A net force directed northward acts on the object for SI] 5. At the end of the SID-second period, the net force drops to zero newtons. WhiCh one of the following statements is necessarily tme? 1:} The object will be moving eastward when the force drops to zero newtons. 1:} The direction of the object's acceleration depends on how fast the object was initially moving. 1:} The change in the velocity of the object will be directed north of west. 1:} The nal velocity of the object will he directed north of east. 1:} The magnitude of the object's acceleration depends on how fast the object was initially moving. An airplane flying at 150 m/s due east makes a gradual turn while maintaining its speed and follows a circular path to fly south. The turn takes 20 seconds to complete. What is the radius of the circular path
