A transverse sinusoidal wave on a string has a period T =28.0 ms and travels in the negativex direction with a speed of 25.0 m/s. At t = 0, a particle on thestring at x = 0 has a displacement of 2 cm and is moving inthe negative y direction with a speed of 2 m/s.

(a) What is the amplitude of the wave?

(b) What is the initial phase angle?

rad

cm/s

(d) Write the wave function for the wave in terms of x (incm) and t (in s). (Be sure to use enough significant digitsto arrive at a reasonably precise formula.)

y(x,t) = cm
