Express the vectors illustrated in Figs. 1-11(c), 1-13, 1-14, and 1-15 in the form R= Ri + Rj+ R.k (leave out the units). 5.7 m -3.2 m 71 m 94 m Fig. 1-13 Fig. 1-14 S = 60 sin 40° = 39 m 60 m 40° 60 cos 40° = 46 m Fig. 1-15

Can someone please help me understand this question and how to get the answer? Two displacement vectors have magnitudes of 5.0 m and 7.0 m, respectively. If these two vectors are added together, the magnitude of the sum is: 1.) equal to 8.6m 2.) could be as small as 2.0m or as large as 12.0m 3.)is equal to 2m 4. or is equal to 12m. Thank you. I am really confused.
