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).

Total 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?

To calculate power, you can use the formula: Power = Work / Time. In this case, the work done is 425 J and the time taken is 10.5 seconds. Plugging these values into the formula, the power expended by the boy to pull the sled up the hill is 40.48 watts.


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.

Cardioversion of 200 joules - how many watts?

To calculate the power in watts, simply divide the energy in joules by the time taken to deliver that energy. If 200 joules of energy are delivered in 0.2 seconds during cardioversion, the power would be 200 Joules / 0.2 seconds = 1000 watts.
