In a large department store, a shopper is on the "up" escalator, which is traveling at a speed of 0.81 m/s. He passes his daughter, who is standing on the identical, adjacent "down" escalator (see figure). A.) Find the velocity of the shopper relative to his daughter in the x-direction. (The angle of the escalators with the ground level is 46.6 degrees.)  B.) What is the velocity of the shopper relative to his daughter in the y-direction?
