Homework Statement
Refer to diagram. Find acceleration of each block:
n1,n2, n3 are coefficients of friction.
if a force of 10 N acts on the middle block, find the acceleration of each.
Homework Equations
F=ma
The Attempt at a Solution
a1,a2,a3 are accelerations of bodies, taken from top to bottom.
Fr1= Friction force for n1
Fr2= Friction force for n2
fr1+fr2=10
7*a1=fr2
2*a2=fr1
7*a1+2*a2=10
the middle block will be stationary with respect to ground.
I can't understand where am I going wrong?
