Express your answer in terms of the variables A, v, , z, t, and appropriate constants. Express your answer in terms of the variables A, v, , a, t, and appropriate constants. Umax = Submit Give Up Submit Give Up Incorrect, One attempt remaining; Try Again Correct

Explanation / Answer

B)

Compare the given equation with,

y(x,t) = A*cos(kx - w*t)

w = 2*pi*f

= 2*pi*v/lamda

maximum speed of a particle, Vmax = A*w

= A*2*pi*v/lamda
