The velocity of the eagle is 7.0 m/s
Explanation:
The motion of the fish is a projectile motion, which consists of two independent motions:
- A uniform motion (constant velocity) along the horizontal direction, where the horizontal velocity of the fish is equal to the horizontal velocity of the eagle
- An accelerated motion with constant acceleration (acceleration of gravity) in the vertical direction
We start by analyzing the vertical motion, using the following suvat equation:
where:
s = 6.1 m is the vertical displacement of the fish
u = 0 is the initial vertical velocity of the fish
is the acceleration of gravity
t is the time
Solving for t, we find the time of flight of the fish:
Now we know that during this time, the fish travels a horizontal distance of
x = 7.9 m
Therefore, the horizontal velocity of the fish is
And therefore, this is the initial velocity of the eagle.

Answer:
There is no short answer.
Explanation:
In theory, the gravitational pull between the planets depends on their total mass and the distance between them. The sun has a mass of kg, Jupiter has a mass of
kg and Earth has a mass of
kg.
Earth is closer to Jupiter than it is to the sun. The other planets that are behind jupiter are gone so that means the sun's pulling force's effect on jupiter is increased drastically since there is no force the balance that and that means that jupiter is going to get closer to earth.
The new center of mass of the new solar system is roughly located between earth and the sun, closer to earth.
I hope this answer helps.
