- Check Your Understanding Suppose that Balto in Example 2.10 leaves the game to attend to more important matter, but Astro Clifford and Dug continue playing. Astro and Clifford’s pull on the toy does not change, but Dug rims around and bites on the toy in a different place. With how big a force and in what direction must Dug pull on the toy now to balance out the combined pulls from Clifford and Astro? Illustrate this situation by drawing a vector diagram indicating all forces involved.There are two forces on the 1.45 kg box in the nverhead view of the figure but anly ane is shown, For Fa- 20.7 N,a - 11.4 ms?, and A- 25.6, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) a direction.
