2D vector magnitude

Answers and reasoning. Review before teaching.

  1. 1. Find the magnitude |v| of the vector v = (8, 6).

    10

    |v| = √(8² + 6²) = √(64 + 36) = √100 = 10.

  2. 2. Find the magnitude |v| of the vector v = (36, 160).

    164

    |v| = √(36² + 160²) = √(1296 + 25600) = √26896 = 164.

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

    50

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

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

    26

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

  5. 5. Find the magnitude |v| of the vector v = (24, 45).

    51

    |v| = √(24² + 45²) = √(576 + 2025) = √2601 = 51.

  6. 6. Find the magnitude |v| of the vector v = (9, 12).

    15

    |v| = √(9² + 12²) = √(81 + 144) = √225 = 15.

  7. 7. Find the magnitude |v| of the vector v = (60, 25).

    65

    |v| = √(60² + 25²) = √(3600 + 625) = √4225 = 65.

  8. 8. Find the magnitude |v| of the vector v = (40, 75).

    85

    |v| = √(40² + 75²) = √(1600 + 5625) = √7225 = 85.

  9. 9. Find the magnitude |v| of the vector v = (8, 15).

    17

    |v| = √(8² + 15²) = √(64 + 225) = √289 = 17.

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

    123

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

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

    205

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

  12. 12. Find the magnitude |v| of the vector v = (105, 100).

    145

    |v| = √(105² + 100²) = √(11025 + 10000) = √21025 = 145.
