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
Fnet = 12 kg * 3 m/s/s
Fnet = 36 N
#$&*
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
20 N = 4 kg * a
a = 5 m/s/s
#$&*
• 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 = 1.5 m/s/s
m = 10 kg
force = 20 N
The total net force is not 20 N it just says a force, and m*a only amounts to be 15 N which means that there are still some forces necessary to have the complete net force.
#$&*
• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
The total force is 15 N and the direction is the same as the direction of the force.
