Please show ALL the steps and the equation used in each situation.

A sinusoidal rope wave travels along the positive x - direction. You are also told that the speed of the wave is 20 cm/s, its frequency is 40 Hz, and that the wave is subject to the following initial conditions: atx = 0andt =0:y = +5cm, and,atx = 0and t = 0: '33; = +10 cm/s (this is the transverse velocity of a point on the rope at horizontal location zero, at time zero). Determine the vertical acceleration of a point on the stringatx = 2cmatatimet = 2s
