Note that if y = A at a given a: and t, then the position 2 represents a point of maximum displacement at the time specified. To practice Problem-Sowing Strategy 15.1 Mechanical Waves. Waves on a string are described by the following general equation 31(9), t) = A cos(km 7 wt). EVALUATE your answer Atransverse wave on a string is traveling in the +3: direction with a wave speed of 800 m/s , an amplitude of 8.00x10'2 m , and a wavelength of 0.460 m .At time t = 0, the z = 0 end of the v Part D string has its maximum upward displacement. Find the transverse displacement y of a particle at a: =1.42 m and t = 0.150 s . In general, the cosine function has maximum displacements, either positive or negative, when its argument is equal to an integer multiple of 7r. When t = 0.150 s , k = 13.7 rad/m , and w = 109 rad/s use the wave equation to select all of the :1: positions that correspond to points of maximum displacement. Check all that apply considering only positive arguments of the cosine function. 0.710m 1.42m 1.54m 1.65m 1.77m 1.88m You have already submitted this answer. Enter a new answer. No credit lost.
