Can't see where I'm going wrong here - would greatly appreciate if anyone can point it out!
I've gotten the other parts of the question right, so I know that:
ω = 125.66 rad/s
A = 2.50 * 10-3m
k = 3.49 rad/m
The wave is moving in the +x direction.
The general equation for the position of a particle on the wave is:
y(x,t) = Acos(kx - ωt)
So this means (please correct me if I'm wrong) that the transverse velocity of a particle on the wave is:
Vy(x,t) = ωAsin(kx - ωt) = (125.66)((2.50 * 10-3m)sin(3.49x - 125.66t)
I'm asked to find Vy at x = 1.35m, t = 0.0625s.
For this I got 2.07*10-4m/s, but I'm told this is incorrect. Where am I going wrong?
