Kim whirls a 10 kg bag, which is connected to a string in a horizontal circle above her head at some unknown constant speed v. Suddenly, the string breaks and the bag flies off and lands 10 m away with a time of flight of 0.5 s. If the string was 1.5 m long, a) What was the speed of the rock before the string snapped? (vertical motion irrelevant) b) Find the tension in the string before it snaps.
