Question

Two children are sending signals along a cord of total mass 0.56 kg tied between tin cans with a tension of 39 N . It takes the vibrations in the string 0.60 s to go from one child to the other.

How far apart are the children?

Answer 1

The mass of the cord is .

The tension in the cord is .

Time taken for vibration of string is 0.60 sec.

The velocity of the transverse wave on the cord is , where is the tension in the cord and .

Velocity of the wave: , where and is the time.

Substitute and

Distance between childrens is 25.07 m.
