A 2 m wire is just taut between two walls. A 1 kg mass hung at its centre depresses it by 5 cm. The wire has 10 g/m. Find the pulse travel time ( $g = 10$ ). (answer in $s$ ).

Answer:

0.02

Solution:

$t = 2 \frac{0.01 \times 2 \times 0.05}{1 \times 10} = 2 1 0^{- 4} = 0.02$ s. Check: $T = \frac{10 \times 2}{4 \times 0.05} = 100$ N, $v = 100$ m/s, $t = 0.02$ s.
