The work done by applying a force in the same direction of motion is force times distance. So in this case W = F x d = 250 x 15 = 3750 J. Power is work divided by time:
P = 3750 J / 10 s = 375 J/s

The work done in lifting the rock is 500 Joules (work = force x distance). Power is the rate at which work is done, so the power expended in this scenario is 250 Watts (power = work / time).

∙ 12y agoTotal energy is (1000 x 4) = 4,000 newton-meters = 4,000 joules
Power = energy/time = 4,000 joules/2 seconds = 2,000 joules per second = 2,000 watts.

What power is expended of 100 N box is lifted the distance 2 meters in 1.0 Sec?
The power expended to lift the 100 N box a distance of 2 meters in 1.0 second is 200 Watts. This is calculated by multiplying the force of 100 N by the distance of 2 meters divided by the time of 1.0 second.
What is the power expended if a boy pulls a sled up a hill is 425 J in 10.5 seconds?
247 W
What is the power expended by a person who carries a 50N moving box 3m in 3 seconds?
The power expended is 50 Watts. Power is calculated by dividing the work done (force x distance) by the time taken. In this case, the work done is 50N x 3m, which is 150 Joules, and dividing this by 3 seconds gives 50 Watts.
A machine lifts a load of 240-kilograms a distance of 120-meters in 45-seconds. How much power is generated by the machine?
If you multiply the weight (mass x gravity) by the height, you get the energy required. (Note: gravity is about 9.8 newton / kilogram.) You then need to divide that by the time, to get the power.
Defined as one joule of energy expended over one second of time?
A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt.

What is the power expended when a barbell is lifted 2.2m in 2 seconds?
The power during the lift is (weight of the barbell in Newtons)/4.4 watts.Note:Power is not "expended". Energy is. Power is the rate at which energy is expended.
What is the power if 35N force 5 Meters and takes 19 seconds to push?
Power = (energy) / (time) = (35 x 5) / 19 = 175 newton-meters / 19 seconds = 9.2105 watts (rounded)
How much power is needed to lift the 200-n object to a height of 4m in 4 seconds?
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts
What power is expended of 100 N box is lifted the distance 2 meters in 1.0 Sec?
The power expended to lift the 100 N box a distance of 2 meters in 1.0 second is 200 Watts. This is calculated by multiplying the force of 100 N by the distance of 2 meters divided by the time of 1.0 second.

It takes 200 N a box 10 meters in 8 seconds how much power is required?
First mulitiply Newton x meter to get the energy (or work) required. Then divide the result by the time to get the power.
What is the power expended by a person who carries a 50N moving box 3m in 3 seconds?
The power expended is 50 Watts. Power is calculated by dividing the work done (force x distance) by the time taken. In this case, the work done is 50N x 3m, which is 150 Joules, and dividing this by 3 seconds gives 50 Watts.
What if your exert 800 N of force in moving a piano 10 meters in 5 seconds how much power do you expend?
Work = (800 newtons) x (10 meters) = 8,000 newton-meters = 8,000 joulesPower = (work) / (time) = (8,000) / (5) = 1,600 watts
What is the power of a 500 newton teacher if she is able to climb a vertical distance of 4 meters in 3 seconds?
Work = (force) x (distance) = 500 x 4 = 2,000 joules Power = Work/time = 2,000/3 = 6662/3 watts
How do you rate the power of a steem engine?
Horse power, kw/h, kilowatts, ftlb, newton meters... any rating of power will suffice
