Answer 1

Hello!

Answer:

$550 \frac{ft.lb}{sec}$

Explanation:

$P= \frac{W}{t}$

And:

$W=F.d$

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 $1 ft/second$

Have a nice day :)
