A single particle in a transverse traveling wave undergoes
simple harmonic motion given by y(t) = (4.20 cm)cos(2.10t). The
wave travels to the left with a speed of 1.30 cm/s.
a) Write an equation for this traveling wave, y(x, t) assuming y
(0, 0) = 0. b) Find the transverse velocity as a function of time
for a particle located at 3.10 cm. c) Find the transverse velocity
as a function of time for a particle located at 5.10 cm d) Compare
your two answers above and comment on why they are different and
what this means physically
