A traveling wave on a string has an amplitude of 0 m and the string element at x =0 and t = 0 has a displacement of 35.2 % of the amplitude and is moving upward. What is the phase constant of the system if the wave is modeled by the equation; y(x, t) = A sin(kx-wt+phi) ?

The equation for the displacement of a stationary wave on a string is given by y = 2 (sin 5πt)(cos 6πx), where x and y are in meters, and t is in seconds.  Determine:  b.  the amplitude of the point P which lies at a distance of 75 cm from the end of the reflection!

A sinusoidal wave is given by:  y= 8 sin (2x - 5t) cm determine the  transverse velocity vy of a point on this wave in cm/s at point x =8 cm for t=3 s.

A sinusoidal wave is given by:  y= 2.0 sin (3.0x - 2.0t) cm determine the velocity of this wave in cm/s with two decimal places please.

Consider a 1 meter-long string with a mass of 50 g attached to a string vibrator. The tension in the string is 80 N. When the string vibrator is turned on, it oscillates with a frequency of 64 Hz and produces a sinusoidal wave on the string with an amplitude of 4 cm and a constant wave speed.
