A crab eater seal jumps onto a horizontal ice floe with an initial velocity of 6 m/s horizontally. There is some friction between the seal's belly and the ice, which amounts to 160 Newton. The mass of the seal is 82 kilogram. The magnitude of the gravitational force is (mass x g, where g as usual is 9.81 m/s2). Determine how far does the seal slide?
