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 Newtons
#$&*
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
Fnet = m * a
20 Newtons = 4 kg * a
a = 5 m/s/s
#$&*
• 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: ->->->->->->->->->->->-> :
Fnet = m * a
20 Newtons = 10 kg * a
a = 2 m/s/s
Without other forces, the acceleration would be 2 m/s/s. There is at least an opposing force causing the .5 m/s/s decrease in acceleration.
#$&*
• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
Fnet = m * a
Fnet = 10 kg * 1.5 m/s/s
Fnet = 15 Newtons
The total of all forces is 15 Newtons, and it moves in an uphill direction.
