1. The problem statement, all variables and given/known data You have a long string, and you oscillate one end, causing a (transverse) wave to propagate along it. The wave's formula is D=0.40sin(7.0x+38t) where displacement D and position x are given in meters and time t is given in seconds. Determine the maximum and minimum transverse speeds of particles of the string. 2. Relevant equations v= omega/k 3. The attempt at a solution I found the wave speed, which is equal to 5.4 m/s, but I am not sure how to find the maximum and minimum speeds from this.
