Question

1. how does the force required to accelerate the wheelbarrow change as the mass of the wheelbarrow increases?

Explanation:

Step1: Recall Newton's second law

$F = ma$ (where $F$ is force, $m$ is mass, $a$ is acceleration).

Step2: Analyze the relationship

If $a$ is constant and $m$ increases, from $F=ma$, $F$ will increase proportionally.

Answer:

The force required to accelerate the wheel - barrow increases proportionally as the mass of the wheel - barrow increases.
