Work = (force) times (distance) = m g H = (75) (9.8) (45) = 33,075 joules

2 minutes = 120 seconds

Average power = (energy) / (time) = 33,075/120 = 275.625 watts = approx. 0.369 horsepower (rounded)

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 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.


Calculate the watts of power expended when a force of 1 N moves a book 2 m in a time interval of 1 s?

The work done on the book is given by the formula Work = Force x distance. Here, Work = 1 N x 2 m = 2 J. Power is calculated as Power = Work / time = 2 J / 1 s = 2 watts. Therefore, the power expended when a force of 1 N moves a book 2 m in 1 s is 2 watts.
