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: F = m*a
F = 12 kg * 2 m/s ^2
F = 24 Newtons
• What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion: F = m * a
20 = 4 * a
20 N / 4 kg = a
5 m/s^2 = a
• 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: Because when you use the equation F = m *a and plug in the values of F = 10 kg * 1.5 m/s ^2 if these were the only factors then F would = 15 N and not 20 N, therefore there must be other forces acting on the object to give you the net force of 20 N.
• What is the total of all those forces and in what direction does this total act?
answer/question/discussion: the total is 20 N and it would be moving in a positive direction
The other forces would have to total 5 N in the direction of motion.
