Question

A rope is stretched to a distance of 10 meters, and a single pulse is generated at one end. The time required for the wave to reach the other end of the rope was 2.0 s. What is the velocity of this pulse?

Answer 1

Velocity of pulse = distance/time = 10/2 =5 m/s.

Answer 2

The velocity of this pulse is 5 m/s

Step-by-step explanation:

It is given that,

A rope is stretched to a distance of 10 meters. The time required for the wave to reach the other end of the rope was 2.0 s. We have to find the velocity of the pulse.

Velocity of the pulse is given by distance covered by rope's stretching divided by time taken for the wave to reach the other end of the rope. Mathematically, it can be written as :

`v=(distance)/(time)`

`v=(10\ m)/(2\ s)`

v = 5 m/s

Hence, the velocity of the pulse is 5 m/s.
