Force = (15 kg)(4 m/s2)
= 60 Newtons

F = M A = (2,000) (4) = 8,000 newtonsThat's about 1,800 pounds of force, or 0.9 ton, which is an awful lot of force.But your 2000-kg car weighs about 2.2 tons, and you've got it doing zero to 60in 6.7 seconds, so it's going to need some serious force!
Assuming the person doesn't need to accelerate to 70 mph, immediately goes from zero to 70 in an instant, he will cover 1 mile in about 1.166 minutes.

No, it takes the same force to accelerate a moving object as it does to accelerate a stationary object, according to Newton's first law of motion. The force required depends on the mass of the object and the desired acceleration.
The force required to accelerate a 2000 kg car at 4 m/s^2 would be 8000 N (Newtons). This can be calculated using the formula force = mass x acceleration.

No, you do not have to use as much force if you accelerate the ball over a longer distance. This means you are slowing it at a lower rate, but take long enough for the slowing to make a difference.

It varies from person to person, but usually, a force of around 4-6 Gs can cause a person to lose consciousness. This force disrupts the blood flow to the brain, leading to a loss of consciousness.

It depends what the situation is. If an object is falling, the weight of the object, which is determined by the object's mass and the gravity, is the force causing it to accelerate. If you're talking about a box being pushed, you could have a person pushing it, which causes it to accelerate, but you also must take into account the force of friction combatting the applied force.
The force required to accelerate the car can be calculated using Newton's second law, which states that force equals mass times acceleration. So, the force needed to accelerate a 900-kg car at a rate of 3 m/s^2 would be 900 kg * 3 m/s^2 = 2700 N.
