question 9 of 25\na force of 115 n is used to move a chair 0.8 m. how much work is done?\n\na. 143.8 j\nb. 92.0 j\nc. 110.2 j\nd. 21.8 j
Answer
Explanation:
Step1: Recall work - formula
The formula for work is $W = F\times d$, where $W$ is work, $F$ is force, and $d$ is distance.
Step2: Substitute values
Given $F = 115\ N$ and $d=0.8\ m$. Substitute into the formula: $W=115\times0.8$.
Step3: Calculate result
$115\times0.8 = 92\ J$.
Answer:
There is no correct option provided in the given choices. The correct work done is 92 J.
