Question

Determine the magnitude of the sum of the two vectors: 2.5i+1.8j; -6i-0.7j

Answer 1

Answer for this question would be: A, 3.67

Answer 2

A. 3.67

Explanation:

1. Add the two vectors (2.5,1.8)+(-6,-.7)=(-3.5,1.1)

2. Find the magnitude using square root of a^2+b^2

sqrt(-3.5)^2+(1.1^2)=sqrt(12.25+1.21)=sqrt(13)=3.67
