Explanation:
The gravitational force between two objects is <u>directly</u> proportional to the products of the masses and <u>inversely</u> proportional to the square of the distance between them. It is known as Newton's law of gravitation.
In mathematical terms it is given by :
Where
M and m are two masses
r is the distance between them
G = universal gravitational constant
The value of G is a universal constant. Its value do not varies from one location to another.

Explanation:
Let east direction is negative and west direction is positive. The acceleration of an object is given by :
Where
v is the final speed
u is the initial speed
t is the time taken
As the car decelerates, the final speed of the car is less as compared to the initial speed. As a result, its acceleration is negative. It means the car travels eastward and slows down. Hence, this is the required solution.
