-Block m1 = 4.0kg and m2 =2.0 kg connected together by a string. The coefficient of kinetic friction between m2 and the surface is 0.2 .

a) Draw all the forces acting on m1  and m2 . Show these force on the above sketch. 

b) Use the drawn forces to find a formula for the net force acting on the system.

 C) Find the acceleration of the system.
