Model: Fixed-Axis Rotation and Point Particle Dynamics
Approach: Begin We begin with free body diagrams for the two objects.

Note that the two forces acting on the bucket each have zero lever arm relative to the center of mass of the bucket. Thus, they have no tendency to produce rotation about the center of mass and so we can justifiably treat the bucket as a point particle. |
For the point particle, we We then write Newton's second law a2nd Law
