Question

Given two vectors A⃗ = 4.40 i^+ 7.60 j^ and B⃗ = 5.50 i^− 2.20 j^ , find the scalar product of the two vectors A⃗ and B⃗ .

Answer 1

Answer:

  7.4800

Step-by-step explanation:

The scalar product is the sum of the products of the corresponding components:

  A·B = 4.40·5.50 + 7.60·(-2.20) = 24.2000 -16.7200

  A·B = 7.4800
