7. A construction worker pulls a box of tools on a horizontal floor with a force of 100 N in a direction of 37.0° above the horizontal. The floor has a coefficient of static friction of 0.21 and a coefficient of kinetic friction of 0.17. The mass of the box and the tools is 50.0 kg. a. Draw a free body diagram for the box. b. How hard does the floor push on the box? c. Calculate the acceleration of the box.
