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 = m * a = 12 kg * 3 m/s^2 = 36 kg * m/s^2 = 36 N
#$&*
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
f_net = m * a => a = f_net / m = 20 kg*m/s^2 / 4 kg = 5 m/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: ->->->->->->->->->->->-> :
20 kg*m/s^2 / 10 kg = 2 m/s^2.
Because I am only getting 1.5 m/s^2 and not 2 m/s^2, then there must be something opposing my force.

• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
10 kg * 1.5 m/s^2 = 15 N. I have a frictional force of -5 N acting against my force of 20 N
f_net = F + Ffrict = 20 N + (-5 N) = 15 N
