Answer:

Explanation:
The force of gravity between two objects is given by:

where
G is the gravitational constant
m1, m2 are the masses of the two objects
r is their separation
In this problem, we have
m1 = m2 = 1170 kg is the mass of each car
r = 28 m is their separation
Substituting,

Answer:
Atomic and molecular collision processes are the physical interactions of atoms and molecules when they are brought into close contact with each other and with electrons, protons, neutrons or ions. This includes energy-conserving elastic scattering and inelastic scattering.
