Question

An object has a moving energy of 25 J. If I do 25 J of work on the object, how much energy does it have now?

Answer 1

Given data

*An object has moving energy is U = 25 J

*The work done on the object is W = 25 J

As the work is done on the object to increase its velocity, then the energy it has is given as

`E_n=U+W`

Substitute the known values in the above expression as

`\begin{gathered} E_n=(25)+(25) \\ =50\text{ J} \end{gathered}`
