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 * a
F = 12 * 3 = 36N

What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
F = m * a
20 = 4 * a
a = 5 m/s^2
#$&*
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 * a
20 = 10 * a
a = 2 m/s^s
The object is moving at 1.5 m/s^2 but based on the above calculation, it should be moving at 2 m/s^2. This would mean that there is another 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 all the forces is 15 N.
It travels in the positive direction.
