2 A box of mass 12.0 kg is placed on a rough floor.
a. Draw a free body diagram to represent the forces acting on the box.
b. Calculate the value of each force acting on the box.

A girl pushes the box along the floor with a force of 35.0 N. The box slides in a straight line with a constant velocity of 0.5 ms^(-1).
c. Are the forces on the box balanced or unbalanced? Explain how you know. (acceleration due to gravity = 9.81 ms²) ​
