    How Does Wood Slow Down a Bullet?

    After much deliberation and calculations I've discovered that the formula to use is in Chapter 8 of my textbook. 1/2mv2=Fd. A bullet of mass 0.0022 kg moving at 488 m/s embeds itself in a large fixed piece of wood and travels 0.56 m before coming to rest. Assume that the deceleration of the...

    How Does Wood Slow Down a Bullet?

    I just went even simpler and used v = Δd/Δt to find time and then a = Δv/Δt to find acceleration. But the time to the last decimal shown on my calculator is 0.001147541 seconds and the acceleration is an enormous number in the four hundred thousands! And depending on how many sigfigs I take from...
