Question

How much work is done on a stationary box that is

moved across a carpet by a person? The box weighs
5N and it is moved 50cm.
What is the energy transfer for this box?

Answer 1

The work is the force times distance:

• Force = 5N
• Distance = 50 cm = 0.01 m

Work = 5N * 0.01m =0.05 Nm

Since work equals to the change in kinetic energy, thus the energy transfer or work is 0.05 Nm

Answer: 0.05 Nm

Hope that helps!
