Final answer:
The maximum particle velocity for the travelling wave described by equation y = A sin(kx - ωt) is Aω, which corresponds to option A.
Step-by-step explanation:
The question pertains to a travelling wave in a stretched string, described by the wave equation y = A sin(kx - ωt). The task is to determine the maximum particle velocity from the given options. The velocity of a particle in the wave can be derived by differentiating the position with respect to time, leading us to v = dy/dt = -Aω cos(kx - ωt). The maximum value occurs when cos(kx - ωt) is equal to 1, which gives us the maximum particle velocity as Aω, corresponding to option A.
