The speed at which the objects were attracted to each other determined by the gravitational pull.
<h3>What is gravity?</h3>
The force of attraction felt by a person at the center of a planet or Earth is called as the gravity or gravitational pull.
The gravitational force, Fg is the attractive force exerted by the Earth on the object that is equal to the mass of the object times the gravitational acceleration.
When the two objects are attracted, the speed with which they are moving toward each other depends on the strength of the pull force. This pull force is the gravitational pull.
Thus, the speed at which the objects were attracted to each other determined by the gravitational pull.

Earth’s mineral resources:
If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces
The cart A experienced the greatest impulse.
The given parameters;
- force exerted on Cart A = 2 N
- time of force action on cart A = 2 s
- force exerted on cart B = 1
- time of force action on cart B = 3 s
Impulse is defined as the product of the applied force and time of action of the applied force.
J = Ft
where;
J is the impulse
F is the applied force
t is the time of action
The impulse experienced by cart A;
J = 2 x 2 = 4 Ns
The impulse experienced by cart B;
J = 1 x 3 = 3 Ns
Thus, the cart A experienced the greatest impulse.
