Hint: Use the standard equation of the wave.
Step 1: Compare the given equation with the standard equation of the wave.
The standard equation of a progressive wave is given by:
This is travelling along positive x-direction.
Given equation is,
Comparing with the standard equation;
1. Amplitude = 5m
4. Wave velocity, where k is wave number and .
From Eq. (i):
For particle, velocity amplitude=
which will be for
