an elk runs a pattern given by the four displačement 3.20 m, and B = 5.10 m and C = 4.80 m. Determine the magnitude and direction of the last displacement is displacement and ends its displacement at the same location, i.e, R, = Ry = 0. {Consider determining %3D

QUESTION 20 Three vectors and their sum are shown in the figure. Here, a= (4.2 m)7-(1.5 m)] 6= (-1.6 m) 7+ (2.9 m)] 2= (-3.7 m)] Find the magnitude and direction of the resultant vector 2 OA 2.76 m and -17° OB 3.50 m and -410 OC 4.22 m and 510 OD.3.18 m and 1350 OE 1.63 m and -22°

1. ANALYTICAL METHOD OF ADDING VECTORS Solve the same problem as PART 1 but this time analytically. START with the values below. DO NOT USE VALUES FROM PART 1. Suppose you first walk A = 12 m in a direction 20° west of north and then B= 20 m in a direction 40° south of west. Let the +x-axis coincide with the easterly direction and the +y-axis with the northerly direction. Note: In this problem, do not round values if you need to use them for calculations in subsequent parts. Rounding errors can propagate and can make your final answer lie outside the tolerance limit of 5% set for this problem. Keep all answers to 4 significant figures.
