Question

Two students 8 meters apart are holding a stretched, coiled spring between them. One student sends a pulse down the string, and they observe it takes 4 seconds for the pulse to go from one e=nd of the spring to the other and then back to it's starting point what is the speed of the pulse on the string

Answer 1

Step-by-step explanation:

Distance travelled by wave = 8 x 2 = 16 m

Time taken = 4 s

velocity of pulse wave = distance / time

= 16 m / 4 s

= 4 m/s
