Homework Statement
A bullet of mass 0.002 kg initially moving at 510 m/s embeds itself in a large fixed piece of wood and travels 0.78 m before coming to rest. Assume that the acceleration of the bullet is constant.
Homework Equations
What force is exerted by the wood on the bullet?
The Attempt at a Solution
In order to find the force, I had to solve for acceleration using the velocity vs function equation: v^2=V0^2 + 2a[tex]\Deltax[/tex]
a=v^2-V0^2/2[tex]\Deltax[/tex]
a=0-(510)^2/2(.78)
I plugged in the numbers to the equation f=ma, but it doesn't work. Can anybody help me?
