1-5 Speed of a sinusoidal traveling wave

A wave traveling on a string is described by the equation

1. the speed of the wave,

2. the displacement of a particle on the string located at x = 0.50 m and at t = 2.0 s, and

3. the acceleration of a particle on the string located at x = 0.20 m and at t = 3.5 s.

a. Speed of the wave = m/s

a. The wave is written in the form

b. To find the displacement, substitute 0.50 m for x and 2.0 s for t in the equation for the displacement

b.    The displacement =  m

c. The acceleration of the particle is

c.  The acceleration= m/s²
