I need help with this assignment, I am mostly confused on part 2, I got part 1.

75 points, and first answer that's correct gets brainliest.

1. 0.4 m/s

2. 1.4875 m/s

Explanation:

1.

Following the law of conservation of momentum, the initial sum of momentum equals the final sum of momentum. Usually, momentum, p=mv where m represent mass and v is the velocity.

Here subscripts 1 and 2 for mass are for ball and table respectively while for velocity, 1 and 2 are the initial velocities of ball and table respectively, 3 and 4 are final velocities of ball and table respectively.

Substituting mass of ball with 0.2 kg while table with 3 kg, since the table is initially at rest then its initial velocity is zero. Also, the initial velocity of ball we substitute with 14 m/s and final velocity of the ball we substitute with 8 m/s then numerically it will be

2.

tex]m_1v_1+m_2v_2= m_1v_3 +m_2v_4[/tex]

Here subscripts 1 and 2 for mass of astronat and space junk respectively while for velocity, 1 and 2 are the initial velocities of astronaut and space junk respectively, 3 and 4 are final velocities of astronaut and space junk respectively.

Substituting mass of astronaut with 80 kg while space junk with 7 kg, since the astronaut is initially at rest then its initial velocity is zero. Also, the initial velocity of space junk we substitute with 11 m/s and final velocity of the space junk we substitute with -6 m/s then numerically it will be

we can see how the government has failed them.

like poles repel so keep pushing north to north and repels funny to see this
