1. A ball with a mass of 200 g is whirled in a circle at the end of a string 100cm long whose breaking strength is 100 N. neglecting gravity, the maximum speed of the ball is approximately. 2m/s 7m/s 10m/s 50m/s 2.A 1-kg object is moving at 10m/s. To double its kinetic energy, its speed should be increased to approximatel
