Homework Statement
A force of 23.52 N pushes and pulls to blocks
as shown in the figure below. The vertical
contact surfaces between the two blocks are
frictionless. The contact between the blocks
and the horizontal surface has a coefficient of
friction of 0.29.
The acceleration of gravity is 9.8 m/s2
What is the magnitude a of the acceleration
of the blocks?
Answer in units of m/s2
Homework Equations
I know its the sum of Fy=N-mg=0 => N=mg
and the sum of Fx= -fk=max
The Attempt at a Solution
fk=ukN=> fk=20.4624
but I do not know how to plug in Fcostheta or Fsintheta and I know those need to be used somewhere
