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 = 12kg* 3m/s^2 = 36kg*m/s^2
#$&*
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
Fnet = m*a
a= Fnet/m
a= 20kg*m/s^2 / 4kg = 5m/s^2
#$&*
• 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: ->->->->->->->->->->->-> :
This is because Fnet= m*a, therefore if you use these variables to find the Fnet you realize that the given Fnet of 20 Newtons is not equal to the calculated Fnet of 15 Newtons (1.5m/s^2 * 10kg) which means that there is 5 Newtons of other forces acting on the system (20Newtons- 15Newtons).

• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
The other forces sum up to be 5 Newtons and they are acting in the direction of your force since the outcome is a positive force in the direction you are pushing.
