Transverse waves on a string have wave speed v=8m/s , amplitude A=0.0700 m , and wavelength lambda= 0.320 m . The waves travel in the -x direction, and at t = 0 the x = 0 end of the string has its maximum upward displacement. a)Write a wave function describing the wave. Express your answer in terms of the variables x and t . b)Find the transverse displacement of a particle at 0.360 m at time t = 0.150 s c)How much time must elapse from the instant in part E until the particle at x= 0.360 m next has maximum upward displacement?
