2) A standing wave in a chord is described by the equation: y (x,t) = 0.31sin (13.2x + 5.9t + 2.4) All parameters are given in international units. a) Calculate the instantaneous speed of a piece of rope located at position x = 0.8m at time t = 3.6s. b) Calculate the speed of propagation of the wave. Indicate the direction of movement with the sign of your answer (+ v if it goes to the right and -v if it goes to the left).
