A .0200kg bullet hits a 5.00kg wood block that is sitting at rest on a rough horizontal surface. The bullet lodges in the block and the bullet and block slide together with speed VA-0.750m/s after the collision. Before the collision After the collision VA 0.750m/s V=? (at rest) ID Even though the surface is rough, why can momentum be regarded as being conserved during the collision? Find the speed of the bullet before the collision.
