Asst 11 question 1

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= m*a

12kg*3m/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: ->->->->->->->->->->->-> :

fnet=m*a

fnet/m=a

20newtons/4kg= 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 there was no opposing forces the acceleration should be 2 m/s^2, but since it is 1.5 m/s^2 that tells me that there is something opposing it.

#$&*

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

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

we are pushing with a force of 20 newtons in one direction at 1.5m/s^2 that means there are opposing forces. Pushing back Im not sure how to calculate it but my guess is that it would be -5 newtons.
