Question

an elevator weighing 6,000 newton move up a distance of 10 meters in 30 seconds.what was the power of the elevators motor in watt and and in horsepower? btw: the part im having trouble with is getting the horse power

Answer 1

Energy added to the elevator (work) = (6,000 N) x (10 meters) = 60,000 joules.

Power = (energy) / (time)  =  (60,000 joules) / (30 seconds)  =  2,000 watts.

Now, here comes the part you've been waiting for:  The "horsepower".

We won't go through the history of 'horsepower', where it came from etc.
All you need to know is how it relates to 'watts'.

Here's that answer:   1 horsepower = 746 watts .

So the power of your elevator motor was

               (2000 watts) x (1 HP / 746 watts) = 2.681 horsepower  (rounded)

Obviously, that unit has nothing to do with real horses, if it ever did. 
It's just another name for 746 watts.

Now I WILL tell you how to remember that number ... because it's such a gas.
This story is not true either.  But I bet you'll remember it, for a while anyway:

From the detailed entries in Christopher Columbus' log during his
first voyage to the New World, modern scientists have been able to
calculate that when running before a wind of 30 mph, the main sail
of the Nina, the Pinta, or the Santa Maria would have developed
almost exactly 2.0 horsepower. 

Columbus discovered America in 1492 .

So each sailing horsepower on that voyage corresponded to 

                                                         1492 / 2 = 746 watts.

Sorry about that.
The devil makes me do it whenever the subject comes up.
