Answer:
For the first one its about 25 feet
Explanation:
Equation: Mass x Velocity = Momentum
Answer: 93 x 13 = 1,209
The velocity of the boat after the package is thrown is 0.36 m/s.
<h3>
Final velocity of the boat</h3>
Apply the principle of conservation of linear momentum;
Pi = Pf
where;
- Pi is initial momentum
- Pf is final momentum
v(74 + 135) = 15 x 5
v(209) = 75
v = 75/209
v = 0.36 m/s
Thus, the velocity of the boat after the package is thrown is 0.36 m/s.

Answer:
The angular velocity is 
Explanation:
From the question we are told that
The mass of each astronauts is 
The initial distance between the two astronauts 
Generally the radius is mathematically represented as 
The initial angular velocity is 
The distance between the two astronauts after the rope is pulled is 
Generally the radius is mathematically represented as 
Generally from the law of angular momentum conservation we have that

Here
is the initial moment of inertia of the first astronauts which is equal to
the initial moment of inertia of the second astronauts So

Also
is the initial angular velocity of the first astronauts which is equal to
the initial angular velocity of the second astronauts So

Here
is the final moment of inertia of the first astronauts which is equal to
the final moment of inertia of the second astronauts So

Also
is the final angular velocity of the first astronauts which is equal to
the final angular velocity of the second astronauts So

So

The bear is white in color because it is a polar bear.
<h3>What are the color of bears?</h3>
Bears are very large carnivorous animals found around the cold regions of the Arctic or North Pole.
The color of bears, may be brown, black or white depending on how far North the bears are found.
Bears found close to the Arctic or North pole are white polar bears.
Based on the description of the house, every side of the home faces South meaning that the individual lives in the North pole.
Therefore, the color of the bear will be white.
in conclusion, polar bears are white in color.
