(4%) Problem 22: An ice skater is traveling in a straight, horizontal line on the ice with a velocity of v = 9.5 m/s in the positive x-direction. The coefficient of kinetic friction between the skates and the ice is uk = 0.21.Randomized Variablesv = 9.5 m/sMK = 0.2125% Part (a) Write an expression for the normal force, Fy, that the ice pushes against both skates together.
