Net force = mass x acceleration

A force F= N is applied to two masses m1=kg and m2=kg which are in contact with each other. If there is a coefficient of friction mu = , then the net force on them is N and the acceleration is given by
= m/s²
Then the force exerted on mass m2 can be determined.
= N
Note that the share of the force necessary to accelerate the second mass is independent of the friction coefficient.
