Question

Find the vector sum of these vectors:
V1 = -5i - 7j + 8k
V2 = 9i - j - 3k

Answer 1

To find the vector sum of V1 and V2, add the corresponding components to get the resultant vector sum, which is 4i - 8j + 5k.

Step-by-step explanation:

The question asks to find the vector sum of two given vectors V1 and V2.

To calculate the vector sum, we add the corresponding components of the given vectors:

• The sum of the i components: (-5i) + (9i) = 4i
• The sum of the j components: (-7j) - (j) = -8j
• The sum of the k components: (8k) - (3k) = 5k

The resulting vector sum is therefore V1 + V2 = 4i - 8j + 5k.
