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: ->->->->->->->->->->->-> :
12 kg*3 m/s^2 =Fnet=36 N
#$&*
What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
20N=a*4kg
5 m/s^2 =a
#$&*
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: ->->->->->->->->->->->-> :
10 kg*1.5 m/s^2 =15 N
We know this because the force need to move the object with the above conditions, but another 5 N of force had to be used to overcome an opposing force of 5 N.
#$&*
What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
The total is 15 N in the direction that the box is moving.
