Question

Given: Each block has masses m1 = m2 =

m3 = m and the coefficient of kinetic friction
is μ. The magnitude of F equals twice the
total frictional force.
Apply a horizontal force F in pushing an ar-
ray of three identical blocks in the horizontal direction.
Find the acceleration.

Answer 1

1. a =g32. a = 3 μ g3. a = 3 g4. a =μ g25. a =g26. a =μ g37. a = 2 g8. a = g9. a = 2 μ g10. a = μ g
