Question

A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.

The work done on the box is ____ Nm, and the power is ____ Nm/s.

Answer 1

Step-by-step explanation:

A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.

The work done on the box is

100

Nm, and the power is

20

Nm/s.

Answer 2

By definition, we have that the work done is given by:

`image`

Where,

F: force in the direction of displacement

d: displaced distance

Substituting values we have:

`image`

Then, the power is given by:

`P = (W)/(t)`

Where,

t: time

Substituting values we have:

`image`

`image`

Answer:

The work done on the box is 100 Nm, and the power is 20 Nm/s.
