The skier passes point A going 17 m/s. From A to B, the radius of his circular path is 6 m. By using Newton’s second law in terms of polar coordinates, determine the magnitude of the skier’s velocity as he leaves the jump at B. Neglect tangential forces other than the tangential component of his weight.
