Friction problem: Two packages are placed on a conveyor belt which is at rest. Between the belt and package A the coefficient of static friction mu_s =0.2 and mu_kinetic = 0.15. Between the belt and package B the coefficient of static friction mu_s =0.3 and mu_kinetic = 0.25. The packages are placed on the belt so that they are in contact with each other and are at rest. Determine a) whether either, or both, of the packages will move and b) the friction force (either static or kinetic) acting on each package.

Friction problem: Two packages are placed on a conveyor belt which is at rest.
Between the belt and package A the coefficient of static friction mu_s =0.2 and
mu_kinetic = 0.15.
Between the belt and package B the coefficient of static friction mu_s =0.3 and
mu_kinetic = 0.25.
The packages are placed on the belt so that they are in contact with each other and are at rest.
Determine a) whether either, or both, of the packages will move and b) the friction force (either
static or kinetic) acting on each package.
