A box of mass m=25 kg is pushed along a rough surface by a force applied of magnitude 40 N directed at 0=45 degrees below horizontal. The coefficient of kinetic friction between the box and the surface is 0.05. What is the magnitude of the normal force between the surface and the box? Provide your answer as a positive or negative number ONLY, with 1 decimal place (e.g. 1.2 or -1.2). Do not write the units (e.g. s or m or m/s etc.) in the answer box. Do not use scientific notation. Your Answer: Answer Question 5 (1 point) M Uu FA A box of mass m=10 kg is pushed along a rough surface by a force applied of magnitude 65 N directed at 0-35 degrees below horizontal. The coefficient of kinetic friction between the box and the surface is 0.06. What is the magnitude of the box's acceleration?
