What force is required to accelerate an object having a mass of 3 kg at 5 m/s2?

For the force in Newtons, and using units of kg and m/s^2 fr mass and acceleration, the answer is given by Newton's secondlaw formula
F = M a 
Memorize this,failing that, get some Henna and write it on your hand. I suggest give memory a try first, you mother would be happier.
F=ma
Force is equal to the product of mass times acceleration.
