2D vector magnitude

Answers and reasoning. Review before teaching.

  1. 1. Find the magnitude |v| of the vector v = (120, 35).

    125

    |v| = √(120² + 35²) = √(14400 + 1225) = √15625 = 125.

  2. 2. Find the magnitude |v| of the vector v = (60, 63).

    87

    |v| = √(60² + 63²) = √(3600 + 3969) = √7569 = 87.

  3. 3. Find the magnitude |v| of the vector v = (80, 18).

    82

    |v| = √(80² + 18²) = √(6400 + 324) = √6724 = 82.

  4. 4. Find the magnitude |v| of the vector v = (45, 200).

    205

    |v| = √(45² + 200²) = √(2025 + 40000) = √42025 = 205.

  5. 5. Find the magnitude |v| of the vector v = (12, 16).

    20

    |v| = √(12² + 16²) = √(144 + 256) = √400 = 20.

  6. 6. Find the magnitude |v| of the vector v = (30, 16).

    34

    |v| = √(30² + 16²) = √(900 + 256) = √1156 = 34.

  7. 7. Find the magnitude |v| of the vector v = (36, 15).

    39

    |v| = √(36² + 15²) = √(1296 + 225) = √1521 = 39.

  8. 8. Find the magnitude |v| of the vector v = (120, 27).

    123

    |v| = √(120² + 27²) = √(14400 + 729) = √15129 = 123.

  9. 9. Find the magnitude |v| of the vector v = (32, 60).

    68

    |v| = √(32² + 60²) = √(1024 + 3600) = √4624 = 68.

  10. 10. Find the magnitude |v| of the vector v = (10, 24).

    26

    |v| = √(10² + 24²) = √(100 + 576) = √676 = 26.

  11. 11. Find the magnitude |v| of the vector v = (48, 20).

    52

    |v| = √(48² + 20²) = √(2304 + 400) = √2704 = 52.

  12. 12. Find the magnitude |v| of the vector v = (14, 48).

    50

    |v| = √(14² + 48²) = √(196 + 2304) = √2500 = 50.
