Seed 11.1
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:
m=12 kg
a = 3 m/s/s
fnet = ma
THe net force recquired would be 36 Newtons
What would be the acceleration of a 4 kg mass subject to a net force of 20 Newtons?
answer/question/discussion:
m = 4 kg
Fnet = 20 N
a = f/m
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:
Because it could not be accelerating against your force unless some other force was acting in the direction of its motion and acceleration.
What is the total of all those forces and in what direction does this total act?
answer/question/discussion:
fnet=ma
fnet = ?
m=10 kg
a = -1.5
The net force would therefore be -15 Newtons acting in the direction you are pushing. Also, it could be looked at as 15 Newtons acting against the direction
you are pusing therefore acting in the direction of the motion of the cart.
