7) Two people push on a box with a mass of 40.0 kg, shown here as viewed from above. Force F₁ has a magnitude of 120.0 N and a direction of 34.0° as measured from the x axis. Force F2 has a magnitude that is unknown, and is directed at an angle of -20.0° from the x axis. The box starts from rest and moves 50.0 meters along the x axis in 8.00 seconds. Find the magnitude of force F2 and find the coefficient of kinetic friction between the box and the floor. (Credit will only be given to a solution with free body diagram and starting with basic equation)
