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 = mass * acceleration

Fnet = 12 kg * 3 m/s^2

Fnet = 36 Newtons

#$&*

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

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

a = Fnet / 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: ->->->->->->->->->->->-> :

If you have a 10 kilogram object accelerating at the rate of 1.5 m/s^2, then the force

would be 15 Newtons. However, this object has a force of 20 Newtons, so there are other

forces acting on the object.

#$&*

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

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

It should need 15 Newtons, but it needs 20, so there are forces in the amount of 5

Newtons working against the 20 Newton force.
