Answer the following based on Newton's Second Law:
How much net force is required to accelerate a 12 kg mass at 3 m/s^2?
answer/question/discussion: ->->->->->->->->->->->-> :
F= m x a
F= 12 kg x 3 m/s/s
F= 36 kgm/s/s
F= 36 N

What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
F= m x a
A = F/m
A= 20 N / 4 kg
A= 5 m/s/s

If you exert a force of 20 Newtons on a 10-kg object and it accelerates in the direction of your force at 1.5 m/s^2, then how do you know there are other forces acting on the object besides your own?
answer/question/discussion: ->->->->->->->->->->->-> :
F = m x a, so if I rearrange the problem to solve for acceleration, then I get the equation:
a= F/m
a = 20 N / 10 kg
a = 2 m/s/s
Seeing that my acceleration should be two meters per seconds squared, I can assume that there is an outside force acting on the object.

What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
The total of the forces acting against my object is 5 Newtons, giving me a net force of 15 Newtons.
