I need a typed answer by keyboard Handwritten answer not allow

Part (a)What is the speed of propagation, in meters per second, of the wave?

Part(b)What is the magnitude of the maximum transverse velocity, in meters per second, of the medium at a given point along the wave?

(7%) Problem 14: The graph below shows the transverse displacement versus time at a fixed position for a traveling wave with a wavelength of 8.27 m. 5.0 4.0 3.0 1.0 y(x, t) (cm) 0.0 -1.0 -2.0 -3.0 -4.0 -5.0
