Answer:

Explanation:
m = Mass of car
3m = Mass of truck
v = Velocity of car
= Velocity of truck
r = Turn radius
Centripetal force is given by
For car

For truck

Dividing the forces we get

So, the multiple of the original force is 
So first of all, you might run out of food, which means that there wont be enough to sustain too many animals/people.
Or, you could simply run out of the space to have any more offspring.
One final one is the introduction of a new predator, which would eat the population, making the growth unpredictable.

Since these two forces are of equal magnitude and in opposite directions, they balance each other. The book is said to be at equilibrium. There is no unbalanced force acting upon the book and thus the book maintains its state of motion. When all the forces acting upon an object balance each other, the object will be at equilibrium; it will not accelerate.
