## Homework Statement

Hi All

Just need some clarification on this problem:

In splitting logs with a hammer and wedge, is a heavy hammer more effective than a lighter hammer? Why?

## Homework Equations

F = ma

M(v-u)=Ft

## The Attempt at a Solution

I would state that the smaller hammer would be more effective. it has a smaller mass which based on netwons 2nd law implies a greater acceleration. This is in turn leads to a greater force acting on the log of wood. The time over which both hammers act will be the same. but as a the smaller hammer has a greater force, this leads to a greater impulse force and invariably a greater change in momentum.

Please feel free to correct my application and analysis.

Regards
