Not enough information. You must also know the change in velocity.
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.
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

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.
There is no specific force required to accelerate an object to a predetermined speed. A smaller force will produce a smaller acceleration, so it will take longer to reach the desired speed. A larger force will produce a larger acceleration, so the desired speed will be reached sooner. But either the large or the small force, or any other force, will produce an acceleration, and cause the object to reach the specified speed sooner or later.
