Friction Practice Problems
Name
1. A 55,0 kg box is pulled by a 325 N Force at an angle of 28.0 degrees above
- the horizontal. The force of kinetic friction is 25.0 N.
Draw a free-body(force) diagram for the box and label the applied
force, the applied force in the x and y direction, the force of gravity, the
force of kinetic friction and the normal force.
