Questions & Step-by-Step Solutions

What is the resultant of vectors (1, 2) and (-1, -2)?
  • Step 1: Identify the first vector, which is (1, 2). This means it has an x-component of 1 and a y-component of 2.
  • Step 2: Identify the second vector, which is (-1, -2). This means it has an x-component of -1 and a y-component of -2.
  • Step 3: To find the resultant vector, we add the x-components of both vectors together: 1 + (-1) = 0.
  • Step 4: Next, we add the y-components of both vectors together: 2 + (-2) = 0.
  • Step 5: Combine the results from Step 3 and Step 4 to get the resultant vector: (0, 0).
