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 = m * a
F = 12 kg * 3 m/s^2
F = 36 Newtons
#$&*
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
a = F / M
A = 20 Newtons / 4 kg
A = 5 m/s^2
#$&*
• 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: ->->->->->->->->->->->-> :
A = F / M
A = 20 Newtons / 10 kg
A = 2 m/s^2
Since the object when moving in the direction of the force is at 1.5 m/s^2, and the actual acceleration is 2 m/s^2, then we know that there are other forces acting on the object besides our own.

• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
F = M * A
F = 10 kg * 1.5 m/s^2
F = 15 Newtons
Total force equals 15 Newtons
