Question

Place the correct answers onto the image.How much power is indicated by each example?

Answer 1

To determine the power in the first option we just need to make the quotient given:

`\frac{250\text{ ft-lbs}}{50\text{ s}}=5\text{ }\frac{\text{ ft-lbs}}{\text{ s}}`

To determine the second power, we first need to convert the minutes to seconds; we know the one minute have 60 seconds and then 4 min is equal to 240 s. Hence have:

`\frac{2400\text{ ft-lbs}}{4\text{ min}}=\frac{2400\text{ ft-lbs}}{240\text{ s}}=10\text{ }\frac{\text{ ft-lbs}}{\text{ s}}`

Therefore, the fist result is 5 and the second result is 10.
