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=15kg*3m/s^2=45N
#$&*
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
a=Fnet/m=20N/4kg=5m/s^2
#$&*
• 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: ->->->->->->->->->->->-> :
With no other forces acting, a=20N/10kg=2m/s^2 This likely means some other force(s) like friction or gravity are effecting the system.

• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
Fnet=10kg*1.5m/s^2=15N This means there is the 20N mentioned earlier and 1 or more forces acting against it totaling -5N. This is also assuming that the 20N is the only force acting in that direction.
