Question

What is the magnitude of the momentum IPA,j of piece A before the explosion? Express your answer numerically in kilogram meters per second A giant "egg explodes as part of a fireworks display. The egg is at rest before the explosion, and after the explosion, it breaks into two pieces, with piece B moving in the positive x direction. The masses of both pieces are indicated in (Figure 1), shown traveling in opposite directions. View Available Hint(s) AZd A,i kg m/s Submit Part B During the explosion, is the magnitude of the force of piece A on piece B greater than, less than, or equal to the magnitude of the force of piece B on piece A? Figure

Explanation / Answer

A) egg is at rest before the explosion, so the momentum must be zero.

Ans: 0 kg.m/s

B) every action produces an equal and opposite reaction. So the two forces must be equal to each other.

Ans: equal to

C) Piece A will be moving faster, since it has less mass, and piece B will be moving slower, since it has greater mass, but the momentums will be the same.

Ans: 500 kg.m/s
