Homework Statement
A 4.32 kg block is placed on top of a 9.16 kg
block. A horizontal force of F = 66.6 N is
applied to the 9.16 kg block, and the 4.32 kg
block is tied to the wall. The coefficient of
kinetic friction between all moving surfaces
is 0.169. There is friction both between the
masses and between the 9.16 kg block and the
ground.
The acceleration of gravity is 9.8 m/s^2.

Homework Equations
ƩF = ma
fs = μk*FN
The Attempt at a Solution
(see attachment for free body diagrams)
ƩF = ma
m = 4.32 kg
atop block = 0
ƩF = Fapplied - fk - T
0 = (44.274) - (7.155) - T
T = 44.274 - 7.155
T = 37.119
Apparently I did something wrong somewhere, but I'm not sure where.
