Find the resultant vector when the following are combined: 2 m west, 5 m east and 7 m west.

• 5 m east

• 4 m west

• 7 m east

• 14 m east

What is the resultant vector if A = 72.4 m, 32° E of N, B = 57.3 m, 36° S of W, and C = 17.8 m, S?

• 15.4 m, 37° W of N

• 12.74 m, 51.15° N of W

• 13.67 m, 45.23° N of W

• 14.98 m, 52.34° W of N

The equilibrant has the same magnitude and direction as the resultant vector.

• True

• False
