Wrong question ..?

#### Explanation:

For the body to be accelerated to 7

we know , work don't in doing so is equal to

W=

This can be altered due the presence of friction force.

To solve this question we have to get at least 1 variables , But here we have got 2 , provided the information is insufficient.
