Are some forces stronger than others?
Yes. For example, the force of a 3-yr-old child pushing a shopping cart is typically less than the force of a freight train pushing the same cart. Similarly, the mutual forces of gravity between the Earth and the same child are less than the gravitational forces between the Earth and her father.
As long as an object at rest is there a force acting against it?
There can be forces acting on an object while it is at rest, as long as the forces cancel each out. For example: a block laying on a table feels the force of gravity pulling it down, but the table pushes up with the same force. Therefore, the forces cancel and the object remains at rest.
When an object is at rest what are the forces acting on it?
You never know. The only thing you know about the forces on an object that's not accelerating is: They all add up to zero, and their effect on the object is the same as if no forces at all were acting on it. That's the same as saying that all the forces on the object are 'balanced'.
What are the forces that resist outside forces?
They are inertia and momentum. If an object is in motion it tends to "try" to stay in motion, and an object at rest does the same to stay put. The forces still act on it, although the forces are slightly weaker.
Can an object at rest start moving with no forces?
An object at rest cannot start moving with no forces.
What would happen if a person was on a skateboard and that person pulled a cart by a cord?
It depends on the frictional forces and the masses. If the frictional forces were the same and the masses were equal, then the cart and the person on the skateboard would both move towards each other. If the mass of the cart were much bigger then the cart would move much less with the skateboarder moving most of the distance, if the cart were very light, then the skateboarder would move very little and the cart would move most of the distance. A higher frictional force in either of the two and the movement would be less for that system.
When the car is at rest what forces accting on car?
None. It is at rest. No forces.

the red cart is at rest with a mass of 0.6kg. The blue cart is moving towers the red cart with a velocity of 2.5 m/s and it has a mass of 0.8kg. After a collision between the two carts what is the velocity of the red cart?
Lolz
If the unequal opposing forces are applied to the cart at the same time what will happen?
The cart will have a non-zero net force and thus the cart will be accelerated, meaning it's velocity will change over time ( f = ma). To find the net force, you would need to vectorially add each individual force.
How do balanced forces affect an object that is at rest?
Not at all. The object is at rest only because the forces are balanced.
What forces makes the go kart stop?
They are aerodynamic drag and the friction between (a) the go-cart and the track, and between the axle and axle-mounts of the cart.
What is the average acceleration of the an cart after 3 seconds?
The answer depends on the forces acting on the cart. Since you have chosen not to provide that information, it is not possible to give a more useful answer.
