Hello!
Answer:
[tex]550 \frac{ft.lb}{sec} [/tex]
Explanation:
[tex]P= \frac{W}{t} [/tex]
And:
[tex]W=F.d[/tex]
F: Applied force.
d: Distance traveled by the object.
Finally, we have that:
t: Time traveled by the object.
The Power or Work/Second of a 1 Hp (Horsepower) engine is the force necessary to vertically raise a weight of 550 lb at the speed of [tex]1 ft/second[/tex]
Have a nice day :)
