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=a*m=3m/s^2*12kg=36N
#$&*
What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
A=F/m=20N/4kg=5m/s^2
#$&*
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: ->->->->->->->->->->->-> :
20N force on a 10kg mass should accelerate it at 2m/s^2.
#$&*
What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
20N to counteract your force and 15N to move the mass at 1.5m/s^2 for a total of 35N
