Question

Figure 5-61 is an overhead view of a 10 kg tire that is to be pulled by three horizontal ropes. One rope's force (F1 = 50 N) is indicated. The forces from the other ropes are to be oriented such that the tire's acceleration magnitude a is least. What is that least a if

?(a)F2 = 30 N, F3 = 20 N;

?(b)F2 = 30 N, F3 = 10 N; and

?(c)F2 = F3 = 30 N?
