Question

amy uses 20n of force to push a lawn mower 40 meters. how much work does she do? show all work to earn full credit.

Explanation:

Step1: Recall the work formula

The formula for work \( W \) is \( W = F \times d \), where \( F \) is the force applied and \( d \) is the distance moved in the direction of the force.

Step2: Substitute the given values

We are given that the force \( F = 20\,\text{N} \) and the distance \( d = 40\,\text{m} \). Substituting these values into the formula, we get \( W=20\,\text{N} \times 40\,\text{m} \).

Step3: Calculate the work

Multiplying \( 20 \) by \( 40 \), we have \( W = 800\,\text{J} \) (since the unit of work is joule, \( \text{J} \), and \( 1\,\text{J}=1\,\text{N}\cdot\text{m} \)).

Answer:

The work Amy does is \( 800\) joules.
