Question

A 0.750-m-long pulse is travelling at a speed of 6.12 m/s in a spring. How long does it take the pulse to pass any point on the spring?

Answer 1

0.122secs

Step-by-step explanation:

Speed = Distance/Time

Given

Speed = 6.12m/s

Distance = 0.750m

Substitute

Time - Distance//Speed

Time = 0.75/6.12

Time = 0.122secs

Hence it takes the pulse 0.122secs
