6. how much power is used if a force of 35 n is used to push a box a distance of 10 meters in 5 seconds?
Answer
Explanation:
Step1: Calculate work done
Work ($W$) is calculated by the formula $W = F\times d$, where $F$ is force and $d$ is distance. Given $F = 35\ N$ and $d=10\ m$. $W = 35\times10=350\ J$
Step2: Calculate power
Power ($P$) is calculated by the formula $P=\frac{W}{t}$, where $W$ is work and $t$ is time. Given $W = 350\ J$ and $t = 5\ s$. $P=\frac{350}{5}=70\ W$
Answer:
$70\ W$
