Question

A woman applies 100 N force for 10 seconds on a box of mass 5 Kg. How much work does the woman do?

Answer 1

The woman does 100,000 J of work on the box

Step-by-step explanation:

To calculate the work done by the woman, we can use the formula:

Work = Force x Distance

The woman applied a force of 100 N for a time of 10 seconds. We need to find the distance moved by the box. Since the box has a mass of 5 kg, we can use the formula:

Force = mass x acceleration

Acceleration = Force / mass = 100 N / 5 kg = 20 m/s²

Using the formula for distance traveled:

Distance = (1/2) x acceleration x time² = (1/2) x 20 m/s² x (10 s)² = 1000 m

Now we can calculate the work done:

Work = 100 N x 1000 m = 100,000 J
