  1. Write something.
  2. Three forces act on a point: 3 N at 0°, 4 N at 90°, and 5 N at 217°.
    1. What is the net force?
    2. What fourth force will put the point in equilibrium?
  3. Inclined Plane Problem
  4. Write something completely different.

algebraic

  1. A push broom of mass m is pushed across a horizontal floor at a constant velocity by a force of magnitude F directed at an angle θ with respect to the floor.
    1. Make a free body diagram showing all the forces acting on the head of the broom.
    2. Find the coefficient of kinetic friction on the broom in terms of the variables m, g, F, and θ.
