A bomb at rest on a horizontal frictionless surface explodes and breaks into three pieces that fly apart horizontally as shown below. Select all of the following statements that must be true after the bomb has exploded.   (1) The total kinetic energy of the bomb fragments is the same as that of the bomb before explosion. (2) The total momentum of the bomb fragments is the same as that of the bomb before explosion. (3) The total momentum of the bomb fragments is zero.

A moving white hockey puck collides elastically with a stationary red hockey puck on a frictionless horizontal surface. No net external force acts on the two-puck system. Select all of the following statements that must be true for this collision.   (1) The kinetic energy of the white puck is conserved (same before and after the collision). (2) The linear momentum of the white puck is conserved. (3) The linear momentum of the two-puck system is conserved.

Two identical bullets are fired horizontally with identical speeds v0 at two blocks of equal mass. The blocks rest on a frictionless horizontal surface and are made of hard steel and soft wood respectively (see diagram below). One bullet bounces elastically off the steel block. The other bullet becomes embedded inside the wood block. Which one of the following statements best describes which block travels faster after the collision?
