A student lifts a weight of $10.0 \mathrm{~N}$ a distance of 0.500 meters. The energy needed to do this work in calories is $(1 \mathrm{cal}=4.186$ Joules)

Question

Quizplus · Accepted Answer

The work done in lifting the weight is calculated using the formula $W = F \cdot d$, where $W$ is work, $F$ is force, and $d$ is distance. Here, $W = 10.0 \, \mathrm{N} \times 0.500 \, \mathrm{m} = 5.0 \, \mathrm{J}$. To convert joules to calories, use the conversion factor $1 \, \mathrm{cal} = 4.186 \, \mathrm{J}$. Thus, $5.0 \, \mathrm{J} \times \frac{1 \, \mathrm{cal}}{4.186 \, \mathrm{J}} \approx 1.19 \, \mathrm{cal}$.
