3.2 Two ropes are tied to a fixed nail. The tension in the ropes is 10N and 20N respectively, while the angle between them is 120degrees. Calculate the magnitude and direction of the reaction to the nail.[8] 3.3. A person going for a walk follows the path shown in Fig.P3.59. The total trip consists of four straight-line paths. At the end of the walk, what is the person's resultant displacement measured from the starting point?
