practice
- Write something.
- Three forces act on a point: 3 N at 0°, 4 N at 90°, and 5 N at 217°.
- What is the net force?
- What fourth force will put the point in equilibrium?
- Inclined Plane Problem
- Write something completely different.
algebraic
- 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.
- Make a free body diagram showing all the forces acting on the head of the
broom.
- Find the coefficient of kinetic friction on the broom in terms of the variables m, g, F,
and θ.
