Unformatted text preview: required to break the cord, which requires a tension T = 150 N. What is the speed of the block when this occurs? Neglect the size of the block for the calculation ( r = 1 . 2 m, g = 9 . 8 m/s 2 ). 2. When the 2-kg bob is given a horizontal speed of 1 . 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 . 1 Figure 1: Question 1 Figure 2: Question 2 2...
