-- The force required to lift the crate is equal to its weight.
-- Weight of the crate = (M x g) = 100 x 9.8 = 980 newtons.
-- Work = (force x distance) = 980 x 3 = 2,940 newton-meters = 2,940 joules.
That's the work done to lift the crate, whether the worker takes a millisecond or
a month to do the job. The amount of work the job requires doesn't depend on
how fast it's done.
The rate at which the work is done is called power.
-- If the work is done in 2 seconds, the power is 2,940/2 = 1,470 joules/second = 1,470 watts.
-- If you're being paid by the hour, decide to stretch it out, and take exactly one hour
to do it, then the power is 2,940/3,600 = 0.817 watt.
-- If you're trying to make a good impression on the boss, and you complete the hoist in
1 millisecond, then your power level is 2,940/0.001 = 2,940 kilowatts = 2.94 megawatts.
-- If you could have completed the job a tiny bit faster ... in 1.97 rather than 2.0 seconds ...
then the power would have been 2,940/1.97 = 1,492 watts = exactly 2 horsepower.
But the amount of work is the same in every case.
w=2.9kilojoules..
80 J
20 crates with 20 eggs leftover
82kg
i done know
w=2.9kilojoules..
twice as much work
100KG
Uhh.. about 3fiddy
100kg
5,2356 dm3
100kg
100kg is about 220.5 pounds.
100kg
80 J
50kg?
Crate engines can provide power to any type of car. A crate engine is very powerful. A crate engine is much more powerful than a regular engine as it produces much more horsepower.
