Answer:
inverse square relationship
Explanation:
Both the Newton's law of universal gravitation and coulomb's law have their force inversely proportion to the square of the distance between the bodies.
 
        
             
        
        
        
Answer:
421.83 m. 
Explanation:
The following data were obtained from the question:
Height (h) = 396.9 m
Initial velocity (u) = 46.87 m/s
Horizontal distance (s) =...? 
First, we shall determine the time taken for the ball to get to the ground. 
This can be calculated by doing the following:
t = √(2h/g)
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) = 396.9 m
Time (t) =.? 
t = √(2h/g)
t = √(2 x 396.9 / 9.8)
t = √81
t = 9 secs. 
Therefore, it took 9 secs fir the ball to get to the ground. 
Finally, we shall determine the horizontal distance travelled by the ball as illustrated below:
Time (t) = 9 secs. 
Initial velocity (u) = 46.87 m/s
Horizontal distance (s) =...?
s = ut 
s = 46.87 x 9
s = 421.83 m
Therefore, the horizontal distance travelled by the ball is 421.83 m

Answer:
 to the right
   to the right
Explanation:
The balls collide in a completely inelastic collision, in other words they have the same velocity after the collision, this velocity has a magnitude V.
We need to use the conservation of momentum Law, the total momentum is the same before and after the collision.
In the axis X:
