Use this equation (v=Δx/t); plug in velocity (0.500 m/s) and the time (2.4 s), then solve for displacement… (Δx=1.2 m)
Answer:
178.4 times
Explanation:
We have Newton formula for attraction force between 2 objects with mass and a distance between them:
where 
is the gravitational constant on Earth. 
is the masses of the 2 objects. and R is the distance between them.
From here we can calculate the ratio of gravitational force between the moon and the sun
We can divide the top and bottom by G and M
So the gravitational force of the sun is about 178 times greater than that of the moon to an object on Earth
the answer is the speed of blue ball after collision is 2.6v
First we shall look at some terms:
Velocity - frequency of change of an objects position.
Acceleration - frequency of change of an objects velocity
Since velocity covers both change in direction and speed, we can asume that the answer is B, not because it's the only one we worked with, but because the others don't make any sense:
A - this is not correct, because a chnage in direction can be done withough a change in speed.
C - The scientific definition of acceleration does include speed, and this is not a reasonable answer.
D - Velocity can change, unlike said in the sentence.
