An 8.0 gram bullet is shot into a 4.0 kg block, which initiallyis at rest on a frictionless horizontal surface. The bullet remainslodged in the block. The block moves into a spring with springconstant 1900 N/m and compresses it by 5.1 cm.
(a) Is the collision between the bullet and the block elastic,partially inelastic, or completely inelastic?
(b) Is the total kinetic energy of the bullet–block systemconserved during the entire process (from just before the bulletreaches the block to when the spring is maximally compressed)? Isthe total momentum of the bullet–block system conserved during theentire process? If you answered no to either
