Question

a force of 25 newtons moves a box a distance of 4 meeters in 5 seconds.the work done on the box is ? NM and the power is. ? nm/ s​

Answer 1

Answer:

The work done on the box is 100 Nm

The power is 20 Nm/s

Explanation:

There is a force 25 newtons moves a box a distance of 4 meters in

5 seconds

The work done on the box is the product of the force and the distance

that the box moves ⇒ work = force × distance

The force = 25 newtons

the distance = 4 meters

Work = 25 × 4 = 100 NM

The work done on the box is 100 Nm

The force moves the box 4 meters in 5 seconds

The power is the rate of work

The power = work ÷ time

The work = 100 Nm

The time = 5 seconds

The power = 100 ÷ 5 = 20 Nm/s

The power is 20 Nm/s
