The following are friction problems. Use the equations in your book/notes to solve them.
1) A desk has a mass of
2) Once the desk above is in motion, what force must be used to keep it moving at a constant velocity if the coefficient of kinetic friction is
3) An object takes 12.3 meters to stop because of friction. Assume no skidding. If the coefficient of static friction is
4) A block begins to slide down a ramp after being elevated to an angle of
