## Homework Statement

A child pushes a block of wood with a mass of 0.72kg across a smooth table. The block starts from a position of rest and after 2.0s it has a velocity of 1.6m/s [forward]. The coefficient of kinetic friction is 0.64.

I have already determined that

F[itex]_{net}[/itex]= 7.06N

F[itex]_{f}[/itex]= 4.52 N

*Find the force with which the child actually pushes on the block of wood*

## Homework Equations

I have no clue what formula to use here in order to calculate this. Any sort of guidance be great! -Thanks

## The Attempt at a Solution

I know that this has something to do with the velocity and it being 1.6m/s after 2.0 but I don't know even know where to being to find which formula to use!
