If it takes 20 n to move a box, how much power will be needed to move the box a distance of 5 meters in 5 seconds?

It will need 20 Watts power to move the box 5 meters in 5 seconds.

Step-by-step explanation:

The power is defined as the work per unit time or the rate of doing work:

W=dL/dt

Where de work L, can be calculated by multiplying the force by the displacement d:

L=F.d

To this example, F and D are known, therefore the work is:

L=20N . 5m=40 Nm

We know that the work is doing within a time of 5 seconds:

W= 40 Nm / 5s = 20 Nm/s = 20 Watts
