Problem#7 Two boxes are connected by a weightless cord running over a very light frictionless pulley as shown in the figure. Box A, of mass 8.0 kg, is initially at rest on the top of the table. The coefficient of kinetie friction between box A and the table is 0.10. Box B has a mass of 15.0kg. and the system begins to move just after it is released.

1. The figure shows a box with mass m1 on a
frictionless plane inclined at angle ?1. The
box is
connected via a cord of negligible mass to another
box with mass m2 on a frictionless plane
inclined at

is frictionless and has
negligible mass and assumes that the setup is on the
surface of the earth.

1. Two boxes are stacked on a frictionless table. M. = 4kg and M, 5kg. The coefficient of friction between the boxes is such that when a 27 N force F is applied to the lower box, the boxes start to slip relative to each other. The system is then restored to rest and force F is removed. A horizontal force F is now applied to the upper box. What is this force's maximum value in order for the two...
