A sinusoidal wave
pls help me on this problem, thanks a lot.
A sinusoidal wave is described by y=(0.30 m)sin(0.20x-40t). Determine the wave speed.

What are the individual parts of the sin wave? 0.30 would be your amplitude, right? Break it down. What is the .20x and -40t?
A sin wave holds the form y = Asin(wt - kx + phase shift) + D, where D is DC offset. w is in rad/sec. K is .20, which is your WAVE number. K = 2*pi*f/c = 2*pi/lambda = w / c. Go from there.
This should probably be moved to the HW forums.
