Question

A wave pulse passing on a string with a speed of 40 cm s−1 in the negative x-direction has its maximum at x = 0 at t = 0. Where will this maximum be located at t = 5 s?

Answer 1

The maximum distance 200 cm along negative x-axis.

Explanation:

Given that,

Speed = 40 cm/s

Time = 5 sec

We need to calculate the maximum distance traveled by pulse

Using formula of speed

$v = \dfrac{d}{t}$

$d=v\times t$

Where, v = speed

t = time

d = distance

Put the value into the formula

$d=40\times5$

$d=200\ cm$

Hence, The maximum distance traveled by pulse is 200 cm along negative x-axis.
