Homework Statement
Two blocks, A and B , are being pushed on a frictionless surface by a froce of 30 N to the right, .Block A has a mass of 2.0kg, Block B, being pushed by Block A is 4.0kg. Calculate the magnitude of the force that block B exerts on Block A.
Homework Equations
f=ma
The Attempt at a Solution
If The total force pushing the blocks as a system is 30 N, then if you treat the objects as individuals 20 N of the force is provided by Block B and 10 N by Block A. So 20 N is the magnitude of the force that Block B exerts on Block A
