Question

A rightward force of 5.0 N is exerted upon a 4.0-kg object for a distance of 2.0 meters. What is the work done on the object? *

Answer 1

Given:

The rightward force, F=5.0 N

The mass of the object, m=4.0 kg

The distance for which the force was exerted on the object, d=2.0 m

To find:

The work done on the object.

Step-by-step explanation:

The work done is the measure of the transfer of energy from a source to an object by the application of the external force.

The work done is given by the product of the force applied and the distance for which the force is applied.

Thus the work done is given by,

`W=Fd`

On substituting the known values,

`\begin{gathered} W=5.0*2.0 \\ =10.0\text{ J} \end{gathered}`

Final answer:

The work done on the object is 10.0 J
