2. Two boxes are stacked on the floor, one on top of the other. The top box has a mass of 10kg
and the bottom one has a mass of 25kg.
Draw free body diagrams for both boxes and label all forces. Remember that the floor
must push upwards on the bottom box for there to be equilibrium.
b. Calculate the forces acting on each box. g = 9.8m/s?
