A block of mass 34.4 kg lies on a horizontal plane. A force F that is inclined 46.2° with the horizontal is applied to the block (pulled the block) causing it to move 14 meters in 9 seconds. If the coefficient of friction between the block and the horizontal surface is 0.37, find the magnitude (N) of the force F. Round off only on the final answer expressed in 3 decimal places.
