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: ->->->->->->->->->->->-> :
Since F = ma, and we are given the mass and acceleration, then the Force = 12*3. The force in this case is 36 Newtons.
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: ->->->->->->->->->->->-> :
Since F = ma, and we are given mass and force, then 20 = 4*a. The acceleration is then 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: ->->->->->->->->->->->-> :
Since Fnet = mass*acceleration, and the mass * acceleration is only equal to 15 Newtons. We know that there are 5 Newtons unaccounted for. This must mean that there are more forces acting on the object then our own.
• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: ->->->->->->->->->->->-> :
The total of all the forces is 15 N, based on the mass and acceleration given. The direction would be in the direction of your force.
