## Question

A string of length 10.0 m and mass 1.25 kg is stretched with a tension of 50 N. If a transverse pulse is created at one end of the string, how long does it take to reach the other end?

### Solution

0.5 s

Tension *T* = 50 N, Length of the string (*L*) = 10.0 m. Mass of the string = 1.25 kg. Therefore, mass per unit length is

The speed of the pulse is

∴ Time taken by the pulse to reach the other end of the string is
