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: ->->->->->->->->->->->-> :
a = F_net/m
3 m/s^2 = F_net/12 kg
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_Net/m
a = 20 N/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: ->->->->->->->->->->->-> :
1.5 m/s^2 = 20 N/10 kg
1.5 m/s^2 = 2N/kg
When we solve the equation, the equation is not equal. We can therefore determine that other forces are acting on the object.

• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
0.75
I think that the forces are acting on the object, since the acceleration is less.
