F = M A = (2,000) (4) = 8,000 newtons
That'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 60
in 6.7 seconds, so it's going to need some serious force!

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

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.

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.
I guess you mean a rate of 5 meters per second squared.You can calculate the force using Newton's Second Law. That is, simply multiply the mass times the acceleration.
It doesn't take any foogems, but it takes 20 FD's.
