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 = (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: ->->->->->->->->->->->-> :

20 N = 4 kg * a

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: ->->->->->->->->->->->-> :

20 N = 10kg * 1.5 m/s^2

15 N

F_net = 20 N - 5 N(difference)

Therefore; 5 in opposite direction

#$&*

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

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

Fnet = m * a,

Fnet = 15 N

This could be in any direction you apply force, the question doesn’t give enough details to answer.
