A bomb at rest explodes into a large number of tiny fragments. The total momentum of all the fragments – (1) is zero (2) depends on the total mass of all the fragments (3) depends on the speeds of various fragments (4) is infinity
(1) is zero Explanation: In an explosion, an internal impulse acts in order to propel the parts of a system (often a single object) into a variety of directions. After the explosion, the individual parts of the system (that is often a collection of fragments from the original object) have momentum.
