In Figure a block of mass m1 = 2 kg sits on a block of mass m2 = 4 kg that sits
on a frictionless table. The coecients of friction between the blocks are s = 0.30 and
k = 0.20 .
(a) Draw a free-body diagram for each block. Clearly indicate the forces.
(b) Determine the maximum horizontal force F that can be applied to to the 4 kg block
if the 2 kg block is not to slip.
(c) If F has half the value found in part (b), and the acceleration of each block and the
force of friction acting on each block.
