Force = mass * acceleration
Force = (15 kg)(4 m/s2)
= 60 Newtons
===========( about 60 times the force needed to push in a doorbell button )
Not enough information. You must also know the change in velocity.
F = M a= (300) x (15)= 4,500 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, 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 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.

it only takes as much force at it would take to bite a carrot, however we have indicators in our brain that tell us not to do so.
take a look at newtons 1st and 2nd laws. Basically if a force is applied on an object in one direction and no other forces are present it will accelerate or decelerate.
It doesn't take any foogems, but it takes 20 FD's.
