Q. Write the equation for a transverse sinusoidal wave with an amplitude of 2.50 cm and an angular frequency of 2.90 rad/s that is moving along the positive x-direction with a wave speed that is 5.00 times as fast as the maximum speed of a point on the string. Assume that at time t = 0, the point x = 0 is at y = 0 and then moves in the y-direction in the next instant of time.
