What is the amplitude of the wave

Assignment Help Physics
Reference no: EM131490803

A transverse sinusoidal wave on a string has a period of 10.4 ms and travels in the negative x direction with a speed of 46.6 m/s. At t = 0, a particle on the string at x = 0 has a displacement of 2.98 cm with a transverse speed of 2 m/s.

What is the amplitude of the wave? Answer in units of m.

What is the initial phase angle? Answer in units of ⦠.

What is the maximum transverse speed of the string? Answer in units of m/s.

What is the wave number? Answer in units of mâ1 .

Please do all the question above.

Also,

(I don't understand what is the difference between speed of 46.6m/s and transverse speed 2m/s. Is transverse speed phase speed?)

(I use y=Asin(kx+wt+phi) because it travels along negative x-axis)

(when t=0, x=0. I think y=Asin(phi)=2.98cm v=dy/dt=Awcos(phi)=2 and I use w=2pi/T)

(then I got tan phi=0.0298*600pi/2======>phi= tan -1 (0.0298*600pi*180/2)

However, my answer is wrong, I dont know what is my problem.
