2D vector magnitude

Answers and reasoning. Review before teaching.

  1. 1. Find the magnitude |v| of the vector v = (9, 40).

    41

    |v| = √(9² + 40²) = √(81 + 1600) = √1681 = 41.

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

    51

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

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

    164

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

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

    15

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

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

    65

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

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

    87

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

  7. 7. Find the magnitude |v| of the vector v = (96, 28).

    100

    |v| = √(96² + 28²) = √(9216 + 784) = √10000 = 100.

  8. 8. Find the magnitude |v| of the vector v = (15, 20).

    25

    |v| = √(15² + 20²) = √(225 + 400) = √625 = 25.

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

    26

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

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

    15

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

  11. 11. Find the magnitude |v| of the vector v = (40, 42).

    58

    |v| = √(40² + 42²) = √(1600 + 1764) = √3364 = 58.

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

    52

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