Sinusoidal wave speed?
A sinusoidal wave on a string is described by the following equation where k = 3.10 rad/cm and ω = 7.50 rad/s.
y = (0.51 cm) sin(kx + ωt)
How far does a wave crest move in 9.5 s?
I can't seem to get the correct answer for this.

k = 2π/λ and ω = 2πf
=> ω/k = λf = v (velocity)
=> velocity, v = 7.5/3.1 cm/s
=> distance traveled by the wave in 9.5 s
= 9.5 * (7.5) / (3.1) cm
= 22.98 cm.
