Question

A giant "egg" explodes as pan of a fireworks display. The egg is at rest before me explosion, and after the explosion, it breaks into too 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. What is the magnitude of the momentum |p_A, i vector| of piece A before the explosion? Express your answer numerically in kilogram meters per second. |p_A, i vector| = kg middot m/s 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? The component of the momentum of piece B, p_Bx, f, is measured to be +500 kg middot m/s after the explosion. Find the component of the momentum p_Ax, f of piece A after the explosion. Enter your answer numerically in kilogram meters per second. P_Ax, f = kg middot m/s

Explanation / Answer

A) PA,i = 0 (since the egg is at rest initially)

B) equal.

According to Newton's third law for every action there is an equal and opposite reaction.

C) Apply conservation of momentum

initial momentum = final momentum

0 = PAx,f + PBx,f

==> PAx,f = -PBx,f

= -500 kg.m/s
