Given the displacement vectors A = (6.00 î – 6.00 ĵ + 5.00 k) m and B = (4.00 î + 6.00 ĵ – 2.00 h) m, find the magnitudes of the following vectors and express each in terms of its rectangular

Answer :

Final answer:

The magnitude of vector A is approximately 9.85 m and the magnitude of vector B is approximately 7.48 m.

Explanation:

To find the magnitudes of the given vectors A and B, we can use the formula:

|V| = sqrt(Vx^2 + Vy^2 + Vz^2)

For vector A = (6.00 î – 6.00 ĵ + 5.00 k) m:

Vx = 6.00, Vy = -6.00, Vz = 5.00

|A| = sqrt((6.00)^2 + (-6.00)^2 + (5.00)^2)

|A| = sqrt(36.00 + 36.00 + 25.00)

|A| = sqrt(97.00)

|A| ≈ 9.85 m

For vector B = (4.00 î + 6.00 ĵ – 2.00 h) m:

Vx = 4.00, Vy = 6.00, Vz = -2.00

|B| = sqrt((4.00)^2 + (6.00)^2 + (-2.00)^2)

|B| = sqrt(16.00 + 36.00 + 4.00)

|B| = sqrt(56.00)

|B| ≈ 7.48 m
