Is the gravitational force between the two objects attractive, repelling, or both? explain how you know

attractive

Explanation:

According to Newton's law of Gravitation, the gravitational force exerted between two bodies of masses and  and separated by a distance  is equal to the product of their masses and inversely proportional to the square of the distance:

Where:

is the Gravitational Constant

and are the masses of the objects

 is the distance between the objects

It should be noted: this force is a central force and is attractive.

your answer would be fusion

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
