Problem A big box of mass m1 sits on the flat surface. There is no friction between this box and the surface. A small box with mass m2 sits on top of the big one. There is friction between two boxes and the friction coefficient is µ. A force F is applied to the big box in the horizontal direction to the right. What is the maximum value of F that can be applied so that the upper box does not slide back during the motion? Acceleration of gravity is g.
In this problem the upper box does not slide back means it will move together with the bigger box with same acceleration.Here we will use the concept of frictional force and Newton's 2nd law of motion.
