Power = (energy) / (time) =
(200 newtons x 4 meters) / (4 seconds) =
200 newton-meters per second = 200 watts

How much power is needed to lift the1 piano and 1 floor in ten seconds?
The answer depends on the mass of the piano and the height of the floor.
How do you find the power of an object that lifted a 50 kg crate in 5 seconds?
First you calculate the energy required to lift the object: potential energy = mgh (mass x gravity x height). Note that your problem statement doesn't mention the height - you need that, too. Energy will be in Joule. Then you divide the energy by the time, to get power (in Watt).
When calculating power what 2 pieces of information are needed?
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
How much power is needed to perform 600 Joules of work in 120 seconds?
7.5 watts
How do you calculate volume for a cube?
You just cube the height....like height to the 3rd power (height*height*height)

A weight lifter has lifted 150 kg to a height of 2 m. He now lowers it carefully to the floor in 5 seconds. How much power is used Remember the force of an object's weight mass and times gravity.?
588 W
When calculating power what 2 pieces of information are needed?
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
How much power is needed to perform 600 Joules of work in 120 seconds?
7.5 watts
Can the power be increased if the same force acted over 50 seconds?
Yes, if the velocity of the object is increased.
A building crane lifts a 1500lb steel beam to a height of 45ft in 10 seconds find the power?
150W
What quantities are needed to calculate an object's resistance?
Voltage, current, or power. You need two out of the three.
How much power is needed to do 1200 Joules of work in 90 seconds?
Power is measured in watts, or joules per second. So in 90 seconds, 1200 joules of work is equal to 1200/90 watts or 13.3 watts.
