    Bullet Hitting Wood the Spring, check of solution

    Thank you for pointing out the error. I have gotten that the Ek system= 50/t (aka. 50/(mw+mb) And now I set the total kinetic energy to equal elastic energy plus work done by friction? Ek=energy lost + Ee The one thing that I don't understand about that is wouldn't the block also be using...

    Bullet Hitting Wood the Spring, check of solution

    mbv1+mwv1=mb+wv .05*200=tv v=100/t So would it only be: Ek(bullet)=Ee + energy lost ? what about when the block slides before hitting the spring?

    Bullet Hitting Wood the Spring, check of solution

    Homework Statement A 50g bullet traveling horizontally at 200 m/s embeds itself in a wooden block, initially at rest, on a horizontal surface (μk=0.1). The block slides 1.2m toward a spring and collides with it. The block compresses the spring (k=600 N/m) by 20 cm. Find the mass of the wood...
