A 2.09 kg block is placed on top of a 10.9 kg
block. A horizontal force of F = 63.3 N is
applied to the 10.9 kg block, and the 2.09 kg
block is tied to the wall. The coefficient of
kinetic friction between all moving surfaces
is 0.117. There is friction both between the
masses and between the 10.9 kg block and the
ground.
The acceleration of gravity is 9.8 m/s2 .
2.09 kg
10.9 kg
= 0.117
= 0.117
F
