What is the maximum transverse speed of the bead

In lab, your instructor generates a standing wave using a thin string of length L = 2.10m fixed at both ends. You are told that the standing wave is produced by the superposition of traveling and reflected waves, where the incident traveling waves propagate in the +x direction with an amplitude A = 2.95mm and a speed vx = 10.5m/s . The first antinode of the standing wave is a distance of x = 35.0cm from the left end of the string, while a light bead is placed a distance of 17.5cm to the right of the first antinode. What is the maximum transverse speed vy of the bead? Make sure to use consistent distance units in your calculations.
