Question

A system engine generating 5 hp is raising a load weighting 2000 lb. How high will the load be raised in 10s?

Answer 1

Answer:

h = 44.5 m

Explanation:

Given that,

Power of the engine, P = 5 hP = 3728.5 W

Weight of the load, W = 2000 lb = 8900  kg

We need to find how high the load be raised in 10 s.

We know that,

Power, $P=\dfrac{W}{t}$

Where

W is work done

Also,

1 Pound = 4.45 newtons earth (N)

$P=\dfrac{F\times h}{t}\\\\h=\dfrac{Pt}{F}\\\\h=\dfrac{8900\times 10}{2000}\\\\h=44.5\ m$

So, the height raised by the load is 44.5 m.
