Displacement vectors of 3 m and 5 m in the same direction combine to ma

a displacement vector that is

in magnitude.

4 meters

2 meters

8 meters

15 meters

The magnitude of the displacement vector will be 8 meters.

Explanation:

Given the vectors:

r= 3 m

s= 5 m

The resulting vector is the sum of the vectors r and s. When we add vectors, the vectors that point in the same direction are added and the vectors that point in opposite directions are subtracted. Therefore, the result will be:

R= r + s = 3 m + 5 m = 8 m

The resulting vector will be 8 m in magnitude and the same direction as the previous vectors.
