MS 2. (Points: 5) A snapshot of a 0.25 Ha sinusoidal transverse wave on a string is shown below. The snapshot is taken at to Os. The wave is moving in the +x direction. a) (Points: 2) if D(x, t) = Asin(kx - wt + Po) represents the wave motion, what is A, w, k and Po, in this function. You must write units with each quantity? ( b) (Points: 1) What is the distance traveled by a crest in the wave shown in 15.0 c) (Points: 2) What is the velocity of the string at x= 0.2m in this graph? And in which direction is the string moving at that position? Compare it to the max velocity of the string
