A 140 kg block is originally at rest. Two forces are applied until it moves an unknown distance s and a final speed of Ufinal = 10 —. The coefficient of kinetic friction between the block and surface is p = 0.5. m 8 F2 F1 0 m Values for the figure are given in the following table. Note the figure may not be to scale. Variable Value Fi 475 N F2 300 N 45 degrees A2 25 degrees Using equations of motion in rectangular coordinates and the Principle of Work and Energy, a. Determine the normal force between the block and surface, N. b. Determine the friction force between the block and surface, f. c. Determine the distance the block must slide, s. Round your final answers to 3 significant digits/figures. N = 1140.13032: ON
