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 kg * 3 m/s^2
F = 36 Nr/question/discussion:

•What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
A = Fnet / m
A = 20 N / 4kg
A = 5 m/s^2
#$&*
•If you exert a force of 20 Newtons on a 10-kg object and it accelerates in the direction of your force at 1.5 m/s^2, then how do you know there are other forces acting on the object besides your own?
answer/question/discussion: ->->->->->->->->->->->-> :
I know there are other forces acting on the object besides my own because the calculations show that the object should be moving at an acceleration of 2 m/s^2. Since it is only moving at 1.5 m/s^2, then there is an opposing force acting upon the object.
#$&*
•What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
20 + (-5N) = 15 N
Fnet = 15N
