    Conservation of Momentum/Collisions

    ...found the initial velocity of the block with the work-energy theorem, and then plugged that into m1v1 = (m1+m2)vf to solve for v1, which was 208.75 m/s (and correct). It looks like I had some conceptual issues with work-energy and inelastic collisions. Thanks everyone for your help!

    Conservation of Momentum/Collisions

    Sorry, forgot to add the question when I was writing it out! It's there now. Harpoon, you're right. Since this is a completely inelastic collision KEf does not equal KEi. Thank you for the correction. Is this why the work-energy theorem would not work here? Because energy is not conserved? It...

    Conservation of Momentum/Collisions

    Hi everyone, this is my first post to the forums. Nice to meet you all and thank you in advance. Homework Statement A bullet of mass 6.00g is fired horizontally into a wooden block of mass 1.21kg resting on a horizontal surface. The coefficient of kinetic friction between block and surface is...
