**1. We know that we need 5000N to drive a nail 2.5 cm into a wall. How fast does a hammer of 500g mass have to be in order to drive the nail in the wall in one stroke?(look at the picture if it is unclear. The 2 cm in the picture should be 2.5cm)**

**2.**

F=m*a

W=F*x

x=distance

**3. I thought it would simply be 10m/s**

since 5000N=10m/s*500g.

But my teacher said it is wrong. Now I have to get to the solution which is 19m/s and show him how I did it.
