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*a = 12kg*3m/s^2 = 36 Newtons
#$&*
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
20N = 4kg*a
A = 5m/s^2
#$&*
• 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: ->->->->->->->->->->->-> :
20N = 10kg*a
A = 2m/s^2
The force should have caused more acceleration to the object, but because it did not you know that there was another force holding/pushing it in the other direction.
#$&*
• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
The total of the forces is .5m/s^2 *10kg = 5N. They are acting in the direction opposite to the direction of the force you applied.
