A person lifts a package weighing 75 N. If she lifts it 1.2 m off the floor, what work has she done?

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 75 × 1.2

We have the final answer as

Hope this helps you

Explanation:

Work can be found by multiplying the force by the distance.

The force of the package is 75 newtons.

The distance the package is lifted off the ground is 1.2 meters.

Substitute the values in and multiply.

1 Newton meter (N*m) is equal to 1 Joule (J).

Therefore, our answer of 90 Newton meters is equal to 90 Joules.

The work done is 90 Joules.
