A ball of mass 400 g is attached to the end of a cord 120 cm long. The ball is whirled in a horizontal circle. The maximum speed at which the ball can be whirled before the cord breaks is 15 m/s. Find the maximum tension (N) that the cord can withstand. Assume that the string remains horizontal during the motion. A ball of mass 400 g is attached to the end of a cord 120 cm long.
