Final answer:
To calculate the acceleration of the wheelbarrow, we need to consider the forces acting upon it: gravity, normal force, and friction.
Step-by-step explanation:
The system to analyze in this scenario is the wheelbarrow full of soil. To calculate the acceleration of the wheelbarrow, we need to consider the forces acting upon it. The forces that need to be included are:
- The force of gravity acting vertically downward
- The normal force exerted by the hill on the wheelbarrow
- The force of friction between the wheelbarrow and the hill
The acceleration of the wheelbarrow can be determined by applying Newton's second law, which relates the net force acting on an object to its mass and acceleration. In this scenario, the net force is determined by vector addition of the individual forces, taking into account their magnitudes and directions.
