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_net= 12kg(3m/s^2)=36N

#$&*

• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?

answer/question/discussion: ->->->->->->->->->->->-> :

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: ->->->->->->->->->->->-> :

F_net= 10kg(1.5m/s^2)=15N

Which means you have a force of 5N that are also acting on the object

#$&*

• What is the total of all those forces and in what direction does this total act?

answer/question/discussion: ->->->->->->->->->->->-> :

5N, in the direction of the force

#$&*

@& Another 5 N in the direction of your force would result in a greater, not a lesser acceleration.*@
