6-4. The coefficients of friction between a
stove
of mass 65 kg and the horizontal floor beneath it are: static, 0.71;
kinetic,
0.64.
(a) What is the minimum horizontal force that
must
be applied to the stove to set it in motion?
(b) Once the stove is moving, what magnitude of
horizontal force will keep it moving at constant velocity?
The FBD for this problem is:
