When the 4-kg bob is given a horizontal speed of 2.5 m/s, it begins to rotate around the horizontal circular path A. If the force F on the cord is increased, the bob rises and then rotates around the horizontal circular path B. Determine the speed of the bob around path B. Also, find the work done by force F.
