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: ->->->->->->->->->->->-> :
Fnet = m * a
Fnet = 12 kg * 3 m/s^2
Fnet = 36 Newtons
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
Fnet = m * a
A = Fnet / m
A = 20 Newtons / 4 kg
A = 20 kg * m/s^2 / 4kg
A = 4 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: ->->->->->->->->->->->-> :
We know when dealing with Newton’s Laws that for every action there is an equal and opposite reaction.
• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
The total force would be 20 Newtons and it is acting in the opposite direction of the initial force.

Good answers on the first couple of questions. You'll probably want to revise your responses on the last couple.
